Garage Tip(s) from Rich Neary. If you have additional tips send them to:
-
To find an electrical short;
Disconnect battery ground cable, put a circuit tester in series with the battery ground terminal and cable. If there is a drain on the battery the tester will light. Remove fuses one at a time and/or methodically disconnect circuits, when the tester goes out, you've found your short.
-
If you have a fuse that pops as soon as you turn that circuit on an easy made short finder is a sealed beam headlight. Make 2 leads coming from the headlight, remove fuse and plug them in where the fuse goes. The headlight will stay lit as long as there is a short, as the headlight now is the load. Start disconnecting things in the circuit, when your headlight goes out, you've found the area of the short.
