I use the Extech 4018 - Amazon.com: Extech 40180 Tone Generator and Amplifier Probe Circuit Finder Kit: Home Improvement
I accidently drilled once through the main power line while installing a house alarm; it took many hours to fix the damage.

Hi, George

Have you used the amp probe to find 12v wires?
My husband has one and we couldn't make it work on the trailer 12v system.???

I used my Extech in RV and at home on any wire, alarm, 120V conduit, LAN, etc. None of these tracers would work on a 12V circuits if tone generator is not properly connected to the wire to be traced. Line voltage, such as 12V DC or AC, will not trigger the receiver, it is the tone transmitter properly connected to the wire to be traced which emits the signal detectable by the receiver. If you had problem with your unit I would assume you had a defective tracer. These tone tracers are very common tools.

I guess what I should have said was that we were trying to do the same thing Kip is- find the physical location of the wire in a cabinet.
My husband's tool did "trace" the wire from point to point- but we already had that info. It's real useful for making wiring diagrams etc., but it doesn't generate a "map" kind of thing.
Maybe his is an older generation of this kind of tracer-

Thanks-

Francesca

The lights are 12v. They receive power from either the battery or the converter. If they were 120v they wouldn't work when dry camping.

I installed a 12v flourescent to those wires and it has worked well for 5 trips.

Well, that's what I think, too. but now that I look at Kip's posts I see that he hasn't really said so.
Seems like if they were 120v you'd be able to feel the housewire through the padding, though.

Your tubing idea's a good one- I've promptly stolen it and added it to my stash of in-case-I-need-this workaround tools!

I generally use tape. It seems to work good enough for most situations.

The only time it seems to fail is when the situation is critical. The hole needs to be "this" deep and no more. Then the bit seems to find something to grab onto, and dig in.
