My "gauges" fuse keeps popping, but I cant find any shorts or grounding problems. Dash lights work, generator gauge works, but no gas, temp, or oil pressure. What the heck? ITs a rally gauge cluster.

try and disconnect the sending units and make sure the wire isn't touching ground, then you'll need to ring out one at a time, this will tell which one it is.

Something is shorted, the harness might be pinched somewhere. When I'm searching for those sort of things, I replace the fuse with an 1156 bulb (solder wires to it, could use a test lamp too). It will light, getting ground from the short. Then I'd unplug the gauge harness and see if it goes out. If not, start tracing the harness.
