Review on 🔌 6-42V Automotive Circuit Tester Tracer Short Circuit Finder Breaker Tracker Detector Probe Car Diagnostic Tools by Charles Butler

I have a construction company so I haul a lot of gear behind my big truck. All of my trailers had working brake lights but no running lights. I've searched and searched and couldn't find the error. Within ten minutes of using this tool, I was tracing the wires from the plug and found a blown fuse. Last week I moved my large enclosed trailer and it blew the fuse again after all other trailers have been fine. So it looks like I'll be using this tool again this weekend to find faulty wires on a trailer.
