blowing fuse

[andy_cook]

just randomly out of the blue my car blew the ignition switch fuse.( the square 30A) i just thought since maybe it was cold it blew. wrong, i changed the fuse and it blew again. i havent done anything to my wiring. havent installed speakers, sterio, switches, nothing. i have changed the fuel pump, starter, alternator the clutch (if theres wires that i couldve messed up there i dont think there is but just a thought). i have no idea what it could possiby be! someone PLEASE help me find the problem. im very desperate to fix this. so if you have an idea what it could be please tell your guys thoughts. is it something that happens on all 240's?

You have a short. use a voltage drop test to isolate it to one area, then go from there.

I understand you're trying to help but if you are all this does is lead to another question. Doing a voltage drop test, doesnt isolate **** except tell you there is a power draw.

Heres what I'd do: Double check all your wiring. Then find a wiring diagram for your the ignition switch fuse and trace the wires. Use the search button also- bet there is some other things to check in a thread or two around there

this is one of those hard to help over the net problems. you just have to trace the circuit wiring and find the short. if you cant, have a knowledgeable friend or take it to a shop/mechanic
