Trying to help a friend out with his 77 Dodge truck. He had to replace both the engine and underdash harness as it fried from the one of the alternator field wires back into the underdash harness to the fuse panel. He had the alternator tested and if course it was fried. He located another complete 77 harness and replaced them, the alternator and voltage regulator. Went to start the truck, idled good then died with no start after that All he has is a test light. I told him check for spark at Nr 1 plug wire then for spark from the coil to the dizzy. No spark there either however he said both terminals on the coil showed power with the key on the run position. So I stopped by to see if I could See anything out of the ordinary but forgot my multimeter. He mentions the ignition switch is a universal for multiple Mopars except 75/76 Valiants and Darts. I spent some time making sure the ignition wires went to according the Chilton/Haynes underdash harness even though the color codes didn’t mstch the underdash harness. Anyway it all seemed to check out. I told him I suspect the coil. Is my analysis correct? If not what else can he check for?
