The Power Probe is the best electrical tester for reducing diagnostic time in all 6- to 24-volt vehicle electrical systems. After a simple hook-up of the Power Probe to the vehicle's battery, you can determine at a glance if a circuit is positive, negative, or open without having to reconnect clips from one battery pole to another. The Power Probe can also test for continuity with its built-in auxiliary ground lead. The Power Probe's switch allows you to conduct a positive or negative battery current to the probe tip for testing the function of an electrical component without the use of jumper wires. The Power Probe is also short-circuit protected; its internal circuit breaker will trip if it becomes overloaded. The Power Probe tests for poor ground contacts instantly without performing voltage drop tests. The Power Probe allows you to follow and locate short circuits without wasting fuses. The Power Probe's long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.
Even if you are skilled with a multimeter (and very few of us are), you will find the Power Probe much quicker and easier to use for the vast majority of electrical diagnostic work on your vehicle and all of its supplemental electrical equipment like the Engel Freezer Fridge, Hella Auxiliary Lights and Horns,Land Rover Genuine Parts Light Switches, Superwinch Winches, and so on.
The Power Probe performs numerous functions, but it has only one real control: the power switch.
A feature that distinguishes the Power Probe II from the original Power Probe is the Power Probe II's selectable audio feature. When the amber LED is lit, the audio function is enabled. To disable the audio feature, simply depress the button below the amber LED.
This audio feature emits a high tone for positive circuits and low tones for negative circuits, and is invaluable when working in bright areas where LED illumination alone is not sufficient. The audio feature may be disengaged when desired, such as for applications where the Power Probe will be connected to circuits for long periods of time and the audio could become annoying.
The Power Probe is also short-circuit protected; its internal circuit breaker will trip if it becomes overloaded. As explained below, the circuit breaker is a valuable diagnostic tool as well as a safety measure to protect the Power Probe from overload.
The Power Probe features a 20' cord that is long enough to reach almost any part of a vehicle.
The end of the cord features snap hooks for connecting the power connectors.
Just connect the power connectors to the cord.
The primary power connections used with the Power Probe are the battery clamps, which connect the Power Probe to the vehicle's battery.
Simply connect the clamps to the cord. The clamps are color-coded to prevent reversing the polarity inadvertently.
Hooking up the Power Probe to the vehicle's battery is very simple. Simply connect the red-colored clamp to your vehicle battery's positive terminal and connect the black-colored clamp to your vehicle battery's negative terminal. Hook-up is now complete.
Another feature that distinguishes the Power Probe II from the original Power Probe is the illumination lights. The front of the Power Probe II's body features two white LEDs for illuminating dark work areas or work areas at night.
When connected to your battery or another power source, the forward LEDs will light white. When working in dark work areas or at night, these navigation lights are invaluable.
At the front of the Power Probe is an LED. When the Power Probe is connected to the vehicle's battery, the LED should be off and not glowing red or green.
With the Power Probe connected, perform a quick self-test. The power switch is a momentary rocker switch located on the Power Probe's body. Flanking the switch are positive and negative markings.
Rock the power switch forward.
The LED will light red. If audio is enabled, you will get a high tone. Let go of the power switch and the LED will turn off and the high tone will cease.
Rock the power switch rearward.
The LED will light green. If audio is enabled, you will get a low tone. Let go of the power switch and the LED will turn off and the low tone will cease. Your Power Probe is working correctly and is now ready for use.
The Power Probe may be used for testing polarity. Touch the probe tip to a positive circuit and the LED will light red. If audio is enabled, you will get a high tone. The red LED and high tone will cease when you break the contact.
Touch the probe tip to a negative circuit and the LED will light green. If audio is enabled, you will get a low tone. The green LED and low tone will cease when you break the contact.
Throughout the vehicle's electrical system, test easily for polarity. Just touch the probe tip to various electrical components to test for polarity. When contacting positive circuits, the LED will light red and the Power Probe will emit a high tone. If it is a bright day and the LED is not visible, the high tone will let you know you are contacting a positive circuit. If you want to disable audio at any time, you may easily do so.
What if you want to switch from testing positive circuits to grounds? You see something like this on your vehicle and suspect it might be a suitable ground for an auxiliary relay, but you're not sure. This would be a dilemma with a standard test light because if the circuit turned out to be a positive circuit and your standard test light was connected to the battery's negative terminal, you would be in for a rude surprise. With the Power Probe, this not a problem at all. There is no need to remove and reconnect the Power Probe's power clips from one battery terminal to another when testing polarity.
Simply touch the Power Probe's lead to the suspected negative circuit. When contacting negative circuits, the LED will light green and the unit will emit a low tone. If you get the green LED and the low tone, the circuit is negative. If you get the red LED and a high tone, the circuit is positive It really is that simple.
Not only can the Power Probe test for polarity, it will test continuity. There is no need to reset the Power Probe's power leads on the vehicle's battery to test continuity.
Continuity may be tested wires and components that are disconnected from the vehicle's electrical system. For example, this Land Rover Genuine Parts Range Rover Classic Headlight Switch is disconnected from the vehicle's electrical system. If you want to know the pin arrangement for your auxiliary light wiring job, it is a simple matter to use the Power Probe to test the switch's continuity arrangement. If you suspect your switch has gone bad for whatever reason, you may also function test the switch using the Power Probe's continuity function.
The Power Probe's continuity function may be function tested easily by clipping the auxiliary ground lead to the probe tip. Obviously, there is going to be continuity between these two components. The LED will light green when continuity is present. No tone is emitted for continuity testing even when the selectable audio function is enabled.
Connect the auxiliary ground lead to the suspected output pin on the switch and the probe tip to the suspected input. If there is continuity between the two pins, the LED will light green. Try the same pins with the switch in the OFF position and see if continuity still exists. Using the Power Probe, function testing switches and other selectable circuits is greatly simplified.
The Power Probe may also be used to function test electrical components that have been disconnected from the vehicle's electrical system. This is an invaluable feature of the Power Probe.
Connect the auxiliary ground lead to the component's negative terminal
Connect the probe tip to the component's positive terminal. The LED should light green, showing that there is continuity through the component's circuitry. If the LED does not light green, then the component is bad.
The power switch will be used to deliver power to the component.
Keeping an eye on the LED indicator, quickly rock the power switch forward and immediately release. If the LED indicator changed momentarily from green to red, you may proceed with your component test.
Rock the power switch forward and hold it down to provide power to your component. With the power switch rocked forward, power will flow from the positive lead on the vehicle's battery into the Power Probe, through the probe tip into the component's positive terminal, into the component and out of the component, through the auxiliary power lead and back into the Power Probe, and back to the vehicle's battery's ground.
If, during the initial rocking of the power switch, the LED indicator turned off or the Power Probe's circuit breaker tripped, the Power Probe has been overloaded and needs to be reset. This could have happened for the following reasons:
1. The contact is a direct ground
or negative voltage;
2. The component is short-circuited; or
3. The component is a high-amperage component, e.g., a starter motor or a winch.
If the Power Probe's circuit breaker is tripped, simply reset it by depressing the reset button on the side of the unit.
Has your winch stopped working and you suspect the remote control is bad? Test it with the Power Probe using its continuity function. If there is no continuity through the switch with its toggle switch depressed, something is wrong with the remote.
You can confirm your suspicions about the winch remote by activating the winch using the Power Probe. Contact the various leads in the remote plug to test for polarity. When you locate the correct pin connector within the socket, deliver power to it using the Power Probe. If the winch works, then your suspicions about the remote's integrity are confirmed.
Has one of your Hella 4000 Auxiliary Lights stopped working but the others still work? One possible reason for the cause could be that there is no power going to that light. Pull the Hella 4000's socket and touch the probe tip to the positive connection and confirm your suspicions. If there is power going into the light, then the cause is likely a burned light bulb or a bad ground. Test the ground by pulling the Hella 4000's connector and testing for ground. If there is ground, then the cause is likely the bulb has burned out. Test for this easily without having to disassemble the entire light by connecting auxiliary ground lead to the Hella 4000's ground connector, and then deliver power to the Hella 4000 by connecting the probe tip to the Hella 4000's positive lead and rocking the power switch forward. Testing for all of these possible gremlins is greatly simplified and easy using the Power Probe.
Oftentimes, electrical components are activated using negative voltage. That is, the component is supplied with power but does not activate because it does not have a ground. Many automobile horns are wired in this fashion. When the horn button's is control depressed, continuity is achieved and power flows through the horns.
The Power Probe may be used to deliver negative power to such components, as the power switch accommodates both positive voltage and negative voltage components.
Contact the probe tip to the negative terminal of the component. The LED will light red. Keeping an eye on the LED indicator, quickly rock the power switch backward and immediately release. If the LED indicator changed momentarily from red to green, you may proceed with your component test. Just as with the positive voltage test, if the LED indicator turned off or the Power Probe's circuit breaker tripped, the Power Probe has been overloaded and needs to be reset. This could have happened for the following reasons:
1. The contact is a direct ground
or negative voltage;
2. The component is short-circuited; or
3. The component is a high-amperage component, e.g., a starter motor or a winch.
A very common reason for electrical failures is a bad ground. The Power Probe may also be used to check for bad ground contacts.
Probe the suspected ground contact with the probe tip. Observe the green LED indicator and listen for the low tone. These two indicators will tell you that you are touching a negative circuit. However, they confirm only that and they do not confirm the suitability or integrity of the circuit as a ground. Just because the green LED and low tone are present do not mean the ground is a true ground.
To test for true ground, keep an eye on the LED indicator and rock the power switch forward and then release.
If the LED indicator light switched from green to red when the power switch was rocked forward, then the point being tested is not a true ground. If the Power Probe's circuit breaker tripped, then this circuit is very likely a true ground. Why? Because the circuit being tested grounded enough amperage to trip the Power Probe's internal circuit breaker. As you can see, the circuit breaker is a useful diagnostic tool as well as a safety measure against overloading the Power Probe.
The Power Probe is also a very useful tool for locating short circuits. In most cases, a short circuit will appear in the form of a blown fuse. Accordingly, the fuse box is usually the best place to start in your search for the short.
Let's say the 10-amp fuse on the left is blown from a short. Use the Power Probe to energize each of the two contacts that hold this fuse (do this with no fuse in the holder). The side that trips the Power Probe's circuit breaker is the shorted circuit. Note the particular wire going to the shorted fuse holder and trace it. Follow the wire in the shorted direction until you locate the short.
The Power Probe II that we sell includes Power Probe's Accessory Kit for maximum versatility. The Accessory Kit includes an extended probe tip for hard-to-reach areas, vehicular 12v power plug, 20' extension cord, and a blow-molded transport case.
The extended probe tip allows reaching into tight spots.
The extended probe tip is identical to the standard probe tip in all but length.
The two probe tips are easily interchanged simply by unthreading them from the Power Probe's body and swapping them out.
The vehicular 12v plug permits use of the Power Probe without hooking it up to the vehicle's battery.
The vehicular 12v plug connects easily to both the Power Probe's primary and extension cords. Just snap it on.
Just insert the 12v into your vehicle's 12v socket. Be mindful that if your 12v plug is ignition-sensitive, then the Power Probe will not operate without the ignition keyed.
Another thing to remember is that you may exceed your 12v socket's fuse rating if you power certain electrical components or test for true ground. Just keep this in mind unless you fancy replacing fuses. If you want to exercise an abundance of caution, you may use the Power Probe only with your vehicle's battery. However, the internal 12v socket is often a very convenient power source for testing small, low-amperage components inside the vehicle.
The Accessory Kit also includes a 20' extension. The Probe's primary power cord is already very long and the extension cord will likely be the least-used item in your Power Probe Kit. But it will be there if you require it.
With the extension cord fitted, it is impossible not to be able to reach to reach an electrical component on your vehicle.
All of the foregoing items are housed in this convenient transport case. Keeping everything in this case makes storage and transport of the Power Probe greatly simplified.
The Power Probe II With Accessory Kit also includes an instruction manual. The Power Probe II is very simple to use, but you must understand how to use it properly. Read the instructions.
The instructions are written in plain English and easy to understand. Diagrams accompany the written text for added reinforcement.
If you have misplaced your instructions or you want a back-up copy, the instructions are also available in in pdf form by clicking on the photo above.
Once you understand your Power Probe II, the above reference chart will likely be all you require to get full use out of it.
Take the diagnostic ability of your Power Probe even farther with the Power Probe Lead Set. The Power Probe Lead Set helps you accurately diagnose electrical problems much faster, as piercing wires is greatly simplified and contacts otherwise out of reach are made accessible. Furthermore, the several different diagnostic leads for the Power Probe are made instantly detachable and interchangeable. The Power Probe Lead Set is the only set of its kind that features both high-current 10-gauge multi-strand leads and gold-plated electrical connectors. The super flexible extensions come in lengths of 1', 3', and 6', and may be combined if required, giving you even greater flexibility in hard-to-reach areas. Two self-centering piercing probes make wire piercing easy and save fingertips from inadvertent puncturing. The large and small probes pierce wires from 28 gauge to 8 gauge while assuring the wire is centered every time. The banana jacks, plugs, and adapters are shrouded for additional safety, and are in the standard 4mm size for compatibility with all circuit-testing equipment.
The Power Probe Lead Set comes complete with a banana jack for easy interchangeability of different tips, probe tip, yellow piercing probe for piercing large wires, green piercing probe for piercing small wires, alligator lead clip, 1' extension, 3' extension, 6' extension, male/male adapter, and female/female adapter. These pieces combine to make the Power Probe even more effective and easy to use.
The banana jack is a device that makes the various leads quickly detachable and interchangeable simply by pulling them of the Power Probe and pushing them back on.
Installing the banana jack onto the Power Probe is very simple. The Power Probe comes with a threaded probe tip.
Unthread the probe tip from the Power Probe.
There is a collar on the end of the Power Probe body.
Remove the collar by pulling it from the Power Probe body. You are now ready to install the banana jack.
When you open your Power Probe Lead Let, the banana jack comes installed on the Power Probe Lead Set's probe tip.
Remove the banana jack from the probe tip.

The Power Probe is now ready to accept the Power Probe Lead Set's various leads.
With the banana jack installed onto the Power Probe, the various leads in the Power Probe Lead Set may now be quickly detached and interchanged without threading or unthreading.
The leads are a push fit onto the banana jack. To detach a lead, simply pull it off.
To install a lead, simply push it on. The probe tip shown above operates just like the standard probe tip on the Power Probe, but is quickly detachable if desired.
Why would you want to detach the standard probe tip? What if you want to pierce a wire for testing? Certainly, you can pierce a wire with the standard probe tip, but it is much easier to pierce a wire with the correct tool. If you have inadvertently punctured your finger while trying to pierce a wire, you know how important the correct tool can be. The Power Probe Lead Set comes with two piercing probes. The green piercing probe is smaller than the yellow piercing probe. The green and yellow piercing probes enable the user to pierce wires from 28- to 8-gauge in size.
The piercing probes feature a hooked end to capture and hold the wire against movement. In this photo, the piercing tip of the piercing probe is fully retracted for easy insertion of the wire.
Turning the threaded end of the piercing probe will force the ram and piercing tip of the piercing probe forward.
In this photo, the ram is pushed forward to hold wire, but the piercing probe remains retracted.
In this photo, the ram is pushed forward and the piercing probe is forward. The degree of piece may be controlled by the amount of threading.
Piercing wire is very simple with the piercing probes.
Simply put the wire into the hooked end of the piercing probe and tighten the adjustment collar to push the ram forward.
In the photo above, the ram is fully forward and the wire is pierced. The piercing probes offer hands-free operation once the wire is pierced.
The pierce is centered every time. Furthermore, the piercing probes permit electrical testing and diagnosis with minimal intrusion into the wiring. There is no need to cut your vehicles wires and resplice them afterward for testing with the piercing probes.
Another very useful lead included with the Power Probe Lead Set is the alligator lead. Some applications feature exposed connectors. In these cases, there is no need to pierce wires for diagnostic work. The alligator lead permits the user to affix the Power Probe to the test site when a third hand is required for other tasks.
Sometimes the test site is out of reach or you need to test two sites far apart. In case cases, an extension are required. The Power Probe Lead Set comes complete with 1', 3', and 6' extensions. These extensions may be combined to form a 10' extension if required. To connect two or more extensions, simply push them together.
Whether you require the standard probe tip, piercing probe, or extension for a particular application, all may be quickly and easily pulled from the Power Probe's banana jack and interchanged as required. No threading and unthreading is required to change tips.
If you have a multimeter and want to increase its usefulness, the Power Probe Lead Set is also usable with your multimeter.
Multimeters feature the same 4mm connector size as all of the leads in the Power Probe Lead Set.
On the left is a Power Probe extension; on the right is a standard multimeter lead. The two feature connectors that are identical in size and fully interchangeable.
Just pull your multimeter's lead and replace it with one of the many different leads in the Power Probe Lead Set.
If you require a lead that holds onto the the piece to the be tested, you may fit the alligator lead. If the alligator lead is too short, you can always combine up to three different extensions to form up to 10' of additional reach.
If you need to pierce a wire for testing, fit one of the extensions and a piercing probe. If you require additional reach, you can combine up to three different extensions to form a 10' extension.
If you come across an incompatibility in your lead connectors with various electrical testers, the Power Probe Lead Sets comes complete with male/male and female/female adapters.
The adapters provide even greater flexibility to the Power Probe Lead Set.
All of the above items fit neatly into the Power Probe Lead Set's transport case.
All items are kept together and neatly organized within the transport/storage case.
