Thanks for all of the input. I have replaced the clutch master cylinder 3 or 4 times to stop leaks. This particular master cylinder has not started leaking yet. I have replaced and spliced in a gunk yard fuse panel years ago. Ground loops are created by grounding from unit to unit to unit, etc. The electronics are grounded to a ground not to each other. I replaced the Instrument fuse position in the panel with another fuse holding circuit after I separated the fuse panel connection at the firewall and pulled it out enough to get to the back side. I bought the truck brand new and after a 400,000 miles, 3 radiators, 4 clutches, replaced fuse panel, u-pull it bench seat, totaled wreck( purchased back from insurance company and completely restored), etc., etc., etc.. I thought the Comanche might have an instrument panel voltage regulator like some of the Fords and other makes, that regulate the voltage to the gauges. I will "do it right and not jury-rigg" it the next time. I hate being "bit in the azz" later on. Thanks again for the constructive input. :doh: :bowdown:
