  • This made troubleshooting a car restoration much easier
Size: GMEM285
The car i was working on had its harness removed when i got it so I needed to literally hook every thing back together including reparing several broke wires, connectors, and shorts. I thought this was cheap enough to get but wasnt sure it would be used more than my multimeter. It made testing so much easier. knowing wether something was hot or not and able to inject power into a circuit to make sure the load was connected properly made this job so much simpler. The cable is long enough i could crawl underneath the vehicle. and its never got disconnected from the battery no mater how much wiggling around I did. The tip could scrape through corrosion to make a solid connection and if I put power into the wrong circuit, it has a audible alert and circuit breaker that would reset after a few seconds. It could power any load on the vehicle even the starter for a the few moments i needed to verify it. Great product. Have no real criticism. possibly wish it had a audible tone when probing. ... show more

  • Cable is made of a stiff wiring and makes it a pain to use
Size: GMEM287
But it functions well and is a great value. I am going to use the cable off my broken power probe.
