have to rev past 4k rpm to charge battery
So I have a 87 s4 na, the alternator is a 110 amp alternator, after having it for sometime I had no issues with it, but then I have been having to rev the engine to charge the battery now right after start up. After that it will probably charge up to 13v or if my headlights and fogs are on it can charge between 13v till12v.
I don't want it to get lower than that cause if I forget to rev it after start up driving under load can be 12v or under and then if I shut it off then turn it on the battery dies.
So any advice will help, thanx in advance

did you wire the alternator up correctly to excite it IF it is a different alternator?
