Tool Aid SG 25100 Short Tester

I bought this and was eager to try it out, so I went to the main harness and began going forward. After passing another harness that fed off of the main line, the needle started pointing the other way, indicating that I had passed the short. I went back to the other wiring harness and it just kept leading me directly to the short. I taped the wire after seeing the wear and replaced the fuse, and it worked. Other than that, everything was fine. The most important thing was that this $32 tool and 5 minutes saved me money. It saved me the trouble of having to leave my wife's car in the shop while it was being repaired. This is a gadget that I would strongly recommend.

It is imperative that you attend school. A parasitical electrical floating short, which normally pops a fuse, was discovered when I purchased it. There was no fuse that blew. It turned out that the problem was caused by a faulty alternator and a depleted battery. but . Hey, I'm proud to say that I've got one in my toolbox. When it comes to detecting OPEN circuits, this tool performs admirably. However, you're only allowed to wear it over a harness in certain places. and if the harness is too tight in a difficult-to-reach location. Homer, don't go. sorry.

I bought this product to help me find shorts in automotive wiring, but when I opened it and read the instructions, it stated that it should not be used on engine or body circuits, which was exactly what I needed. It kind of defeats the purpose, doesn't it? Also, the relay in the cup between the wires says 10 amps, so I assume I won't be able to use it on circuits larger than that.

This was purchased to help diagnose a Land Rover Discovery 2's intermittent fault. However, whatever mechanism this employs to limit short circuit current appears to be sufficient to energize the circuit, causing the fault to disappear whenever the circuit was connected.

It didn't work after that. The tester lasted about an hour and a half. I pulled back the black cap ends after it failed to cycle and discovered that the circuit breaker was a 10 amp breaker. I was putting a 20-amp circuit through its paces. Before you buy one of these types of testers, make sure you know what kind of breaker is in it and what you need it for. Hopefully, this company will issue a refund or resolve the issue. If SG Tool Aid refunds me, I will update my review.

I ordered a short finder for a car I was working on that had a short that three different garages couldn't seem to find. I simply pulled the blown fuse from the affected circuit and plugged the short finder into it. I did have to get a wiring diagram from the autozone website in order to figure out which wire the meter should be connected to. Simply run the meter along the wire while keeping an eye on the needle; it will point in the direction of current when you get close to the short; when you get close to the short, the needle will point straight up and down; and presto! You'll find the solution to your issue there. Unfortunately, I had to remove the dash to fix the problem; however, the short finder reduced my troubleshooting time by at least half. I can't imagine not having it; it's a must-have for any tech or DIY enthusiast.

I had a short in my Tahoe that was driving me crazy, and I was about to give up when a coworker suggested I try one of these. In less than ten minutes, I was able to locate the short beneath the sill plate. Needless to say, it saved me a lot of time and sanity by preventing me from removing unnecessary panels, so I bought one right away. It's probably not something I'll need very often (hopefully), but it's nice to have.

There are no batteries required! Built to last, and unlike many other products, it will actually fit back into the case provided after the first use! br>br>In our neighborhood, we have a Snap- This model, as well as the slightly more expensive 25300 model, are both available from the same dealer. This is a good indicator of the product's build quality and dependability. br> Unfortunately for me, it failed to detect my electrical problem, which could be in the truck's PCM (control module) and isn't a complete dead short (about 5 amps), so it doesn't generate the heat required to activate the tool's relay and, more importantly, the magnetism in the circuit to allow detection by the meter. I'm keeping it in any case! br> Amazon, as usual, provided a prompt delivery.
