I am having an intermittent electrical problem I can't seem to find and I am wondering if anyone has any ideas. 88 K30 and the 20 amp fuse for the factory gauges keeps blowing on me. Volts and oil pressure guages are both working fine and fuse will pop at random. Sometimes goes for days, sometimes will go in minutes. Can't find anthing visibly wrong in wiring. Anyone know where circuit goes between fuse and cluster and where is this sucker shorting :mad3:

That circut goes everywhere! Sewrious I believe it is all over the damn place. If I remember correctly its pink or pink/white. Have you done any work on the truck anywhere recently? Anything.
That circut powers almost everything thats ignition on. The same circut runs through the firewall for something too cant remeber what. Maybe alternator. You need a shcematic.
