Fuse keeps blowing in the temp, gas guage, tach and shift light circuit

[Jim S]

Why are electrical problems always rooted behing the dash?!!  Any thoughts on why this fuse keeps blowing? I'm thinking about just wireing a whole new set of wires for these four items and bypass the old circuit.  But looking at the wireing diagram it appears it runs through the courtesy light and cigar lighter too.  Any tips are welcome.

To me this sounds like an occasional “ground out” due to a frayed wire… a wire that has been chafing against a piece of metal, and is now occasionally grounding out to it… blowing the fuse.

A real pain in the - - - to find sometimes!

Good luck!
