Hello Folks. I have a '81 Pontiac Parisienne, 305 Hcode engine. Recently the instrument lamp circuit (" ins lmp " on fusebox ) fuse was blown; resulting in dashboard lights out and headlights left on warning bell not sounding. I replaced fuse ( tough to get to - in top left corner of fusebox ), but it blew again ~3 hours later as I was driving.
Questions: What shoul I be looking for to remedy this? ( intermittent short somewhere? ) The instrument panel is printed circuit I believe so it's probably sound. I replaced heater core and spark plugs last week -- the only recent work on car.
- Could I get away with a crude workaround to problem by replacing the 5 amp. fuse with a 7.5 amp. fuse? Or will this fry the circuit?
Please reply to NG. Thanks, JS
