I just bought this truck, started troubleshooting. Tonight I finally found the hazard flasher over behind the glove box, swapped with turn flasher in the fuse panel , turn signals still work, still no hazard or brakes, before I got this far I already repalced the turn signal switch, live and learn, i could have sworn I had 12 volts at the brake stop switch before replacement, I also saw in a schematic that Fuse #1 15 amp should be hot at all times. I measured tonight and no voltage at all, pulled the fuse and checked socket with DVM on both sides to good ground, no voltage. Wondering if the mating connector for the new signal turn switch did not seat good. ??? Im close but its late and I'm tired , time to retire for the night. Any input greatly appreciated, I have a 351 Windsor , 5 speed manual, tow package, I looked very hard and did not see any fuse panel in engine compartment. I pulled and checked every fuse with ohm meter in fuse box.
Bert, I was on the phone last night with my old friend , a mechanic that works at a Ford Garage, he asked me the same question, I saw no such box. the only box was the Towing trailer box that had the ECC plug and a couple other plugs, no fuses at all, from front to back is the washer resevoir, then the air filter, then the trailer towing setup, no fuses anywhere, I looked last night like I was painting it there but could not find ?? I could have sworn I had the 12 volts prior to putting in the new turn signal switch, ??? but now, no voltage at either side of Fuse #1 in box in cab. Thanks for your help
Would you know of the size fusible link wire (gauge for these) I found them all at the starter relay. there are 2 yellow ones that branch off to 2 seperate wires, then a large green to alternator and another one too.
Well Bert, I loosend the nut on the relay starter and the 2 spade end on the yellow wires fell right off, the other wire had a completely burned out fuse link, the green wire to the alternator was burnt and spade end fell off, I ordered some fusible link wire today and will redo the whole set of links and go from there.
Bert, well , walk away, think, come back, look, etc, so tonight put up on hoist, grab ground cable from motor, was cut right off. Bought new cable tonight , will install tomorrow, am 99% sure I found problem, will let you know
