I've been through about 5 fuses now trying to figure out WTF is going on with this thing, but i'm clueless. My 84 Berlinetta keeps blowing the taillight/gauge cluster fuse. I can stick a new fuse in just fine, interior lights work just fine...But just as soon as I turn on the headlights, it blows the fuse. Anybody got any ideas on this problem? I've got no ideas toward what could be causing this. Any help is deeply appreciated.

 

My mom had that same prolem in a pontiac. Turned out to be the headlight switch. Also check you bulbs.
