blowing fuses

I have a 1978 F-250 that keeps blowing the instrument panel fuse. Is this most likely the board on the cluster or a wire? The instrument panel light is the only thing not working. The gauges and blinkers work fine.

I'm not sure what would be more or less likely. On something 44 years old I'd guess a wire has lost insulation somewhere and is shorted. You could test this by disconnecting the battery, then providing 12v + - to the wires leading to the light's 12v + - and see if it lights up.

The folks that know about this sort of thing don't often visit the "New Member Introductions" forum. You'll probably get a lot more answers posting in the "1973 - 1979 F-100 & Larger F-Series Trucks" forum.

Welcome aboard!
