I do have a Haynes, it's been super helpful. This is not the original alternator but the battery is brand new and the voltage regulator is brand new(ly remanufactured)My guess is that your alternator isn't charging. That might be a voltage regulator problem, but, it sounds like you now have it hooked it up properly. I wonder if your battery was ever over-charged, or if the rectifiers in the alternator were damaged? Do you have a Hayne's manual?
