This site should help & give u some ideas.
-As said the 1 wire goes to positive side of battery.
-A smaller pulley will get the rpm on the alternator up to the speed required to start charging
-I don’t think a positive ground alternator exists so as said for ur gauge to work when converted to negative grounding u need to reverse the original negative / positive connection on your electric gauge to match ur 6 or 12 conversion to the neg ground alternator
- I believe there are external exciters that will let it charge immediately on any rpm.
