Wiring Diagrams Desperately Needed
Issue: Alternator not charging. I've tried several iterations without success. My coach is a 79 but the engine is a 90 454TBI 7l4L. At this point, I'd love to get my hands on any schematics from 79 and newer or to know where I can find them. The alternator is a Delco Remy 1101138 100 amp that can accomodate up to four wires on the plug. Tested it at AutoZone and O'Reilly's and checks out fine. There is a remote starter solenoid (Ford) and a 100 amp battery isolator with four terminals, i.e., Batteries 1&2, Alternator and Excitation terminals. I'm beginning to think I need to add an alternator indicator lamp to start the alternator. Thought I could do this by having the I (wire) go to the ignition but no joy! Unfortunately, people where I live who could offer assistance. I just love to see anything out there that I can compare and work will have to stop when the cold weather arrives. Please help if you can.
