Best open circuit finder

Martin Owner/Technician New York Posted   Latest  

Hello team,

I am trying to locate a broken wire across 20 ft or more wire and pneumatic harness looms on a trailer. Looked at a few brands but what is your preferred choice for this application. I need a tool that can be fixed to an individual wire and traced along its length. Much of what I am seeing seems best for the phone or cable installers, need something with an automotive application.

pour moi, j'utilise la sonde de puissance 4 et dans cet outil, il y a une option que vous connectez à votre rupture de fil, vous la marchez tout le long et elle cessera de sonner là où le fil est cassé Circuit Tracer & Short Finder ECT3000

Honestly, I use one that was designed for cable and phone guys from Ideal and it works well. After all copper is copper.

i use the power probe short finder and it works well. The last time it used it on a motorhome to trace the remote generator start button. The wire was broken due to rat damage on the backside of a cabinet panel. It sends a pulse down the wire and uses the other piece to pick up the pulse alone the wire harness. If the wire is spliced off to multiple places can make it harder to focus on which…

Don't know, I only work on them occasionally. I worked on that one because my boss knows I can find and fix most electrical stuff.

I don't know what the best is, but I have the older power probe kit and have been satisfied with it, I would buy the newer model if it broke. It is the only one I have ever used so I don't know how it compares with others. I like how you can change the beep on or off for open or short so you can wiggle test.

A roll your own version would be a 5 pin relay. Connect pin 86 to ground, pin 85 to pin 87a extend a pigtail from this junction, pin 30 to batt. Connect the pigtail to the wire under test. Use a handheld AM radio to listen for the static buzz along the wire. Depending on the difficulty of accessing the harness, the half split method may be fastest on such a short section. After visual inspection…

Good day folks, I decided on the Power Probe ECT3000B as that was the tool of choice on this forum. I look forward to using the tool and its other features. Should be in hand tomorrow.
