Its labelled as the Clock, Radio, and Dome Light fuse and its annoying not having a clock/music. Everytime I put a new 15A fuse in, it blows.. sometimes instantly and sometimes within a couple hours.

I think this means I have a short somewhere but how do I go about fixing it?

 

isolate the short. you need a multimeter and some diagrams

 

The first thing to look for is anything installed that wasn't there when the car was built. Aftermarket radio, and so on. I found a loose wire in a customer car behind the aftermarket radio that would wave around and ground out every once in a while.

I have quite a few of those.. I remember having some loose wires from the head unit install but I wrapped them in electrical tape. I'll double check.


About the multimeter and diagrams, I found a bunch here: http://www.binghamtonlife.com/...l.htm
but dont really know what to look for. Should I just touch the multimeter points to the pos and neg wires of my head unit? then clock? then dome light? If one doesnt read 12V then do I need to replace some wiring?
