Prepare to leave your other tools on the bench. Once you connect Power Probe tools to your car battery you will have access to an amazing variety of diagnostic functions.
What does it do?
With the press of a switch you'll have an instant hot lead or ground lead. Use the probe tip and ground lead simultaneously to power up components right in your hand. Instantly check components for continuity as well as identify positive, negative and open circuits without re-polarizing hook-up clips. Locate shorts without wasting fuses.
Power Probe 3 manual
Power Probe provides innovative Technology, Engineering, and Knowledge solutions for technicians and consumers.
Power Probe 3
Power Probe 3 uses a 20ft cable which attaches to the vehicle’s battery, allowing the user to perform an electrical test anywhere in, or around the vehicle.
The PP3 is a Voltmeter and Continuity Tester, with Audible & Visual indicators along with two LED headlights to light up your work area. This circuit tester also supplies Battery Voltage or Ground to activate components. The housing is sleek and feels great in your hand. This powerful time-saver tool is perfect for every level of technician.
Features :
- Ability to Power Up Components ● Audible Tones
- Voltmeter ● 12 - 24 Volt Range
- 20 ft. Power Cable ● Bad Ground Indicator
- Continuity Tester ● Short Circuit Indicator
- Relay and Component Tester
While the PP3 is in Power Probe Mode. Contact the probe tip to a NEGATIVE circuit. The green negative sign “-” LED will light. If the audio feature is turned on, a low pitched tone will sound.
While the PP3 is in Power Probe Mode, contact the probe tip to a POSITIVE circuit. The red positive sign “+” LED will light and the voltage reading of the circuit will be indicated on the LCD display. If the audio feature is turned on, a high pitched tone will sound.
1. Connect the PP3 to a good battery.
2. Clip the auxiliary ground clip to the trailer ground.
3. Probe the contacts at the jack and then apply voltage to them. This lets you check the func-tion and orientation of the connector and trailer lights. If the circuit breaker tripped, that con-tact is likely a ground. Reset the circuit breaker by letting it cool down (15 sec.) and depress-ing the reset button until in clicks into place.

This makes finding the right fuses for tapping into a breeze. Also an easy way to test if motors/lights work without messing with wires.Only major issue is that using it on 24v doesn’t always work and I’ve burned out 2 probes already.

I was skeptical at first but read a lot of reviews and did a lot of research. From what I gathered it was a must have tool. The reviews were right, it is a must have tool. My multimeters now collect dust. Does everything an auto mechanic needs for electrical repairs and diagnosis. Plus provides 12v power or ground. I would recommend getting the test leads with it, makes it even more universal and convenient.

I'm a diesel and heavy equipment mechanic. I use this tool twice a week. It gets me out of a bind every time. I recommendthe wire piercing attachments also. Makes it easier to send power through the wire. Especially in those tight places.
