I am trying to do the 1g to 3g alternator swap on my 1983 6.9 F250. I have a few questions and I am probably just overthinking things but I want to do it right.
1st issue is that my old external voltage regulator only has 3 places with wires going into it. The white and black wire that ran from the old 1g alternator runs past the voltage regulator and goes to a relay on the passenger fender by the headlight and then a couple red wires run back from the relay and run into the main harness. What its this for? Do I need to worry about doing anything with this wiring? (See pictures in next post)
2nd question is about the green wire that gets ignition power and runs thru the ammeter on the dash. While stumbling around cyberspace trying to figure out my 1st question I came across a couple posts saying that the ammeter on the dash would not be able to handle the 3g alternator and would burn out? Has anyone had issues with this?
Thanks for any help!
