the answer to you wiring problems
hey man, i have an 83 bronco and my wiring to the alternator was meesed up to. i spent months trying to figure it out, every wiring diagram in the world wont help you. save yourself the headach. gm makes a 1 wire alternator and they make adapters for ford. go to a performance shop, not csk or autozone, and ask for a 1 wire alternator for an 83 ford bronco. it will prolly be chrome, itll have hook up for field and ground, ignore them, run like an 8 guage wire from the positive post on the alt, directly to the positive turminal on your battery. then get you 8mm socket ready, rip that darn regulator off and throw it in the trash. then you can capp off i think it was like 3 wires that you wont be needing anymore. dont forget to hook up your ignition wire, its a fat wire i think its yellow, maybe red, to the pos post on your started relay. now you can hook up lights, sound system, wutever, and you dont have a headache. let me know if it works for you.
