• Brian I was looking up alt. wiring on internet I have a question if you could help I put a 1 wire alt. on my 1963 Buick Riviera I ran a wire from term 1 on the alt. so my amp light would still work. I took the voltage reg. off removed some wires but the #4 term has a small blk. pur. striped wire that in my wiring dia. service manual shows that it is a res.wire I don’t know what to do with it could please help??? Thank You

  • If I remember right that resistance wire was for the regulator to excite. You shouldn’t need it.
