Hi to all.
I have this Fluke voltage tester and since it's very sensitive I want to use it to trace wire on the car.
This tester can detect voltage from 45 to 405 Hz. I'm looking for advice about a device like this transmitter. I didn't find anywhere the specific of this transmitter. Otherways I can build my own transmitter (but I need a scheme) with low voltage output. The goal is to avoid damaging any circuit in the car controller. Most of them are protected against reverse polarity but I don't want to risk.

The Fluke is not designed for, nor is it compatible with the tone generator from that tone and probe set. Fortunately, the probe from the set is. You can use it as long as the wires you are tracing are not live, nor bundled too tightly. The signal induced into surrounding wires may be indistinguishable form the one the tone set is attached to.

But, if you just need to trace it as a harness to the end, and the wires are separated there, it shouldn’t be a problem.

 

The correct search phrase is wire tracker (not tracer) - oh those Cheeneeses in their sellpages!
The cheapest cost 3.5 USD and sure is not worth to try scratch the ass through the nose, just buy and use as it is well proven and trustable solution. Example of equipment in link https://www.aliexpress.com/item/100...393919!sea!LV!0!AB&curPageLogUid=KV3edjI6dup9

 

I am sorry that I have not been able to express my thoughts well. It was never a money issue. I'm just looking for a suitable tool that doesn't emit a signal that would cause damage to the car control units. Of course I have to be sure of that. If I also work on an old machine ( Example 2015) I don't want to Break the engine control unit, for example. It could cost up to €1000 to repair the damage.
Basically, does anyone know the characteristics of the signal used by this type of equipment?



When you try to follow a wire, 99% of the time it arrives at a control unit or in a utility.
