Find Short Circuits the Easy Way?

A typical automotive "short finder" is an entirely different breed. These have been around in some form since "I was a kid" (born in 48). They consist of a circuit breaker with a "likely" a resistor to limit current, and a magnetic meter works like a compass. You hook the clip lead breaker unit from power to the shorted circuit, and the internal breaker starts cycling, like a flasher. This sets up an on/off magnetic field around the wire. You run the meter along the wire, and it deflects differently or not at all when you get to or pass the short. Outfits such as KD tool have made these for decades
