Anyone recommend a low voltage

Wand tester for 12 volts or below?   Im redoing my wiring under the dash and I have the 12 volt tester with
the light but I don't want to cut up wires just to determine what is what.   I see there quite a few 110 AC wands out there but no luck finding 12 volt for automotive.   Thanks Steve69

Re: Anyone recommend a low voltage

I don’t know if a wand type tester for 12 VDC. I still like the testers with a ground clamp and light bulbs. Mine has a rip sharp enough to penetrate the wire insulation without destroying it.

If you don’t have the wiring manuals for the car, I suggest you buy one or download from the internet. Print them out as 11x17 if possible. They will provide a good road map and a place for your comments. The comment will cut down on figuring out what you’ve already figured out 3 days ago!!!

Re: Anyone recommend a low voltage

I been looking for one of the "pocket ones" that you just touch the wire and it shows current or not. I think it is a simple neon bulb deal. O'Riellys is no-go butt the sales guys said Lowes(of all places!) has them.
The search continues.

Re: Anyone recommend a low voltage

Thanks for the links Guys.   I tried at Menards and Harbor Freight with no luck.  There's one in that Autozone  link that looks like it might work.   Im going to go over there and check them out. 

Thanks

Re: Anyone recommend a low voltage

You won’t find one for DC. AC has a frequency that cause induction and that’s what you pick up. Like transformers, they only work on AC or pulsating currents

X2 on the whole proximity probe thing.  AC yes - but on DC you are pretty much stuck with insulation piercing probes

Re: Anyone recommend a low voltage

Thanks Guys!   I was wondering why there weren't any out there.  Thanks for the explanation!

   I have some diagrams of the 1969 wiring.  My problem is my own wiring I did 20 years ago and wondering what I spliced here and there...LOL   My memory is not the same as 20 plus years ago.

Hahaha......you’re not alone.....I started taking my car apart in 1989. All of that was forgotten along with the final disassemble before the body shop in 2012. I took lots of pictures too......rarely had one that showed what I needed!!
