How to find direct shortage placement - Mystique Mercury Cars & Trucks

Answers :

You can't just put a fuse in because it will keep blowing. So instead, jump the fuse with a flasher relay. This will cause pulses you can pick up with a cheap circuit sensor you can get at a place like Harbor freight. When you trace the circuit and it stops pulsing, you found the short.
An alternative is to disconnect things one at a time, until the short goes away.
If you don't have a spare flasher, you can just use a test light. If you jump a fuse with a test light normally it is half brightness, because it is in series with something in the circuit.
It will be full brightness if there is a short, because the light will be going straight to ground an not be in series with any other resistance load.
