I ordered my short finder, for a car i was working on, it had a short that 3 different garages could'nt seem to locate, i simply pulled the blown fuse out of the affected circuit, and plugged the short finder into the circuit. I did have to get a wiring diagram off of the autozone website, so i would know what wire to run the meter along. You just run the meter along the wire while watching the needle, it will point in the direction of current, when you go past the short it will point back the other direction, when you get right on top of the short, the needle will point straight up and down, and presto! there you will find your problem. Unfortunately i had to remove the dash to fix the problem, the short finder cut my troubleshooting time in half or more.Now i cant live without it, a must have for any tech or DIY'er.

This is an inexpensive but effective tool for testing and tracing automotive electrical shorts. Without this tester, you could be replacing the fuses on your vehicle all day long. You put this short tester in place of the fuse of the suspected short circuit and it will trip the tester causing it to reset itself in a few seconds. Each time it re-sets itself, you can use the Amp meter to trace the direction of the short wire. Great little tool to have in your tool box.

This little tool helped me a lot to find my electrical problem, but not in the way intended.

My tail light fuse kept blowing out every time I put one in. I tore up my dash and trunk trying to find the problem, and couldn't. I bought this tool.

The tool works in place of a fuse, and allows current to flow for a few seconds before shutting off. It resets after several seconds, and current flows again. This feature allowed me to determine that my tail lights did not have a short, because the lights came on when the current flowed. The problem was a defective bulb in my parking light in the front of the car.

So, the tool didn't find a short, but it allowed me to run current and see the problem was not a short to my tail lights.

The short finder gauge is confusing, and the instructions on the gauge are contradicted by the written instructions. There is nothing in the instructions that explains that the current is not always flowing -- we heard some clicking, but only realized the thing was tripping when the tail lights would come on and then go off. The gauge can only work while current is flowing, so it would be nice if the instructions made this clear. Also, to use in place of a mini fuse, you have to break an old fuse to get the metal tabs out, clip the tool's leads onto them, and then insert them in the fuse box. Clumsy. Surely they could come up with a simple adapter that would make this easier.

Still, I would not have solved my problem without this tool.

I used this with a 12 volt test lamp and a circuit chart from my OEM manual, and within minutes, I found a shorted wire that was giving me nothing but grief. This is an outstanding tool. Better still, it's made in the USA. None of that Harbor Freight garbage here.

Had a short in my Tahoe that drove me nuts and I was about to give up on it when a coworker told me to try one of these. I was able to find the short under the sill plate in 10 min. Needless to say it saved a lot of unnecessary panel removal and my sanity so I immediately got one of my own. Probably something I wont have to use very often (hopefully) but its nice to have it when you need it...

This device makes it a rather simple process to locate a short. Just run the sensor along the wire until the unit signals that the short has been located.

I Seen this tool being used on realfiesrealfast.com and the way they dimenstrated it was the best I have ever seen and I had to get me one and for the price of it, I think it is a steal!! I think that it is the best tool made for finding a active short if you cannot afford the more expensive tools out there. I love it!!!!!!!
