SG Tool Aid 25300 Short Circuit Detector

The only way IMHO to pinpoint shorts in trucks and busses where you have a lot of area to cover. I've used these types of detectors for many years and couldn't even begin to calculate how much time they have saved. The thing I like is the audio signal. You can hook the tool up to the fuse panel (I normally make ends that fit into the panel fuse slots for the plastic blade type fuses by breaking a plastic fuse apart and using the metal ends to plug into each side of the circuit in the fuse panel I'm testing, this allows you to hook the alligator clips up. When there is a short the buzzer will cut on and off as the circuit breaker in the tool opens and closes. This allows you to hunt for the area where the short is located by moving wires and harnesses or unhooking switches and components throughout the vehicle. When the buzzing stops you know you have located the area where the short is. Then it's just a process of elimination.

Good quality, shipped fast

Did the job tracking down a short in a 1937 classic car. Short was a wire pinched under the license plate trim to the license plate light. Would have taken a long time to find and a lot of fuses with out this tool.

This product works well at finding shorts. However you must have significant knowledge of electrical systems in order to use it. It is not for a novice.

good ,but old school and slow

I have tried to use this product many times and it hasn't helped me at all. I have lost confidence in this product. It's easy to use but has never found me one bad wire yet. I tend not to use it anymore unless I have no time constraints whilst doing the job. Even then I don't really trust the results due to poor results before. Wish It had some sort of electrical buzz when a short is found rather than just a sweeping gauge.

Good Quality

works well
