Please help me with my wiring nightmare!
I have a 77 ford F250 highboy. i love the truck but the wiring is ugly from years of jerry-riggin. my problem now is that a few weeks ago my aulternator went so i replaced it along with my battery because it was shot to, and my voltage regulator. before i put the aulternator in i had it bench tested and it put out 14.5 volts, but when i put everything on my truck and tested the voltage it was only putting out 12.1 volts, which is not enough to run my truck for long (a week or so using no accesories). i traced all my wires from my aulternator to my battery, and i even replaced my starter selinoid a few months ago. this thing has had me and everyone that has looked at it confused so if you have any info please post a thread or you could call me anytime at (412) 716-4629
