Features:
  • This professional DC 6-42V circuit tester is a must-have for automotive repair, home wiring, and industrial maintenance. It effortlessly locates circuit breakers, traces broken wires, detects current leaks, and tests continuity—all without damaging wire insulation. The perfect open & short finder for electricians, DIYers, and auto technicians to solve electrical faults in minutes.
  • Equipped with a high-sensitivity transmitter and receiver, this circuit breaker finder tool delivers crystal-clear test results via bright LED lights and distinct beeping tones. A built-in low-battery indicator (flashing red light) prevents unexpected shutdowns mid-test. Its anti-interference design eliminates background noise, ensuring you get accurate readings every time with zero guesswork.
  • Easily pinpoint open circuit breakpoints using the adjustable sensitivity feature (3 modes). Set the transmitter to the down position— a flashing green light confirms an open circuit. The receiver emits a full signal and rapid beep in normal areas; the signal weakens or vanishes exactly at the breakpoint for precise fault localization.

Does anyone have an opinion on clipping tight alligator clips to an insulated wire? With most automotive wires being smaller gauge.. i feel like a high likelihood of biting through the insulation like almost certainly. Anyone direct experience, thoughts?
Won't bite through, even need to really force backprobe pins through

Since this is free repair advice day...
My analog gas gauge on the dashboard is almost always reading Full. Would this be a better choice than a multimeter to test if is is the instrument cluster or something going to the gas tank.
Thanks !

Someone let us know your experience with this device. All reviews prior to March 2026 pertain to a different product. And almost all reviews since then were free vine reviewers. And the ones that weren't were one star.

My glove box light stayed on draining the battery so I just removed the bulb
I had something similar happen with the light on a visor once; however, the bulb was soldered in place.

Thats unlikely a short or it would blow a fuse. Usually a defective device like a radio that keeps draining power slowly.
Try the Telematics Control Unit.

Had a similar tool in my cable tracing for networking, see if this is any better. 3 vehicles here have some sort of parasitic drain that normal troubleshooting steps cannot locate. See if this is capable of finding a short to ground or whatever my issue is as winter is coming and tired of disconnecting batteries... did the 1 fuse at a time trick with meter that usually works, some of these newer vehicles have over 100 fuses and it gets time consuming... see what learning curve is on this tool and look for videos... for $20 worth a shot..
Try The TCU. I had that issue where it stays on.

Use the meter so you can get voltage/resistance values. Your float is stuck in the full position or you got a short/open tricking the gauge to read so.

So the reviews of 1 and 2 stars seem to be for a camper plug adapter? I think I will pass

Royalty Auto on YoutTube did a long diag video on a parasitic drain on a vette I think it was. They used a thermal camera to pick up the heat signature after the car has enough time for everything to sleep.

Only if the insurance was half price...
Still be less than for a new car.
You can place the lesser used vehicle (or both) on a low mileage plan.

Could be the PCB in the instrument cluster.
My jeep had a fluctuating bouncing speedometer.
I changed out speed sensor, but it didn't fix the issue.
Eventually, I pulled the cluster and replaced the small PCB board with one from the junk yard cluster.
Not hard...just some of the 1990s plastic clips were brittle and snapped off.

A new car is almost 50K. Just buy two crappy cars so as long as one is working you can fix the other one.
Insurance kills that idea

Was looking for a similar tool for home use. I have a no-power outlet at an end-of-circuit outlet and Cant determine why. Bummer …

There are some special Piercing Probes for that or alligator clips and a paperclip may work
