Review on 🚗 Power Probe IV - Red (PP401AS) Car Diagnostic Test Tool with Case & Acc, Digital Volt Meter, ACDC Current Resistance Circuit Tester and Fuel Injector Tester by Kevin Henry

Great tool for hobbyists! I totally love this case. I really like that you can just feel and see if there is tension or mass. I really like that you can throw ground or voltage in a circuit with a switch. Today it helped me fix a backup camera I installed on my wife's truck. I hooked up the whole system to find out it doesn't work. I have used a volt meter and verified that there is no voltage to the head unit which is telling the head unit to turn on the rear view camera screen. I used the power sensor to throw 12V DC into the back of the radio on the return conductor that also powered the camera. The camera turned on and the display switched to the rear camera. I went back to the back of the truck and found and fixed this problem. Then I tried the system again, found it was getting power, the main unit switched to the camera, but I had no video display. I groped around and found that I don't have enough land now. Troubleshooting made super quick and a lot of fun. I also like the two LEDs on the probe body, they give a lot of light when you need it, very handy! I can't wait to use it again. I wasn't sure I wanted to spend money on this as I had a very good Fluke voltmeter... and thought I could do almost anything I needed without buying this unit... I'm so glad that I bought it and I will buy again. A+++
