Yeah, the only law I remeber from physics in "Newton's Law", like when I drop a heat exchanger it accelerates toward the ground, unless it encounters my head first, which of coarse proves "Murphy's Law"
Several others have pointed out my mistake about an increase in resistance causing enough heat to blow the fuse. I did have the pump jumpered with a 30 amp fused 10 ga wire that went directly from the pump to the battery, I first dissconected the pump from the wiring harness. With this "road side" engineering the pump ran fine, unfortunatly it also ran with the engine off.
Today things went well, I had removed my relay board, cleaned it with the Dremmel and soldered all the riveted contacts. I also disconnected the Aux Air valve. The Aux Air wires appear O.K. and that entire ignition harness has been rebuilt, so maybe it is an internal short in the AA regulator as someone else suggested?
Next week I'll figure it out, but a bad AA would explain the problem only occuring when the engine is hot.
P.S. When I say the "ignition harness" I mean the one that has the oil light, coil +12V, starter wire, reverse lights, tach wire, and +12V for the AA. I Used 16 ga wire and soldered them into the facory socket thingy after un-soldering the factory wires. Looks nice if I do say so my self.
