Hi
I was wondering if anyone was using any type of tone generating wire tracers to find the location of breaks in an open wire in a wiring harness and if so which one seemed to work best. Thank You

I have one of these is sold under different brand names I have only used it once and the instructins aren't that clear I am not 100% sure I have used it properly as the result was pretty mixed as I lost the signal about 5 feet in a very thick wiring harness



Paul has a Youtube video on the Power Probe equivalent

I have a cheap one for finding a break in underground dog fence. It works quite well for that. I've thought about trying it on vehicle wiring but have yet to do so. If I get a chance soon I'll try it & report back.

I have the power probe one and it's kind of dicey.
The signal can be leaked into adjacent wires and get you chasing your tail.

Thanks for the feedback everybody. I have the ECT3000 and it works good on small harnesses but as I mostly work on heavy trucks as soon as I try to use it on the larger harnesses inside frame rails it really tells me nothing. Probably a good tool, just won't work in those situations.

I use this on from GTC on heavy equipment and big looms and has worked for me. I like it better than the power probe ECT, but maybe because I’m less familiar with it, which means a lot when using these. Whenever someone pulls the powerprobe out of their toolbox I say no thanks I’ll go get my gtc out of the truck
Like Noah said, you must make sure you don’t start following a signal up a branch, you must know the circuit and isolate it as much as possible.

I’ve also located an open with this by KD tools, I thought it was nice to actually see a needle move while looking for the break.
