Alternator

I have a 3 wire now, but will be switching to a 1 wire, alot neater under the hood, no regulator needed its inside the alternator. The main thing is how much amp draw will you have. Add up all amps you could ever use at one time and have your alternator larger than your worst case senareo. I had the issue with the kill switch not working at the track, I would pull the charging wire before the run and and hook up after to charge the battery. When I have the 1 wire alternator it will run to the positive post at the battery and the rest of the car power will break after the battery with the kill switch. I found alot of info out by Google searching "one wire alternator". I hope this helps.
