Re: alternator help please?
Adding a second or third alt is not hard or expensive. I have four alts under the hood of my van. The chevy 140 amp one wire alt makes it easy and you can get them from a junk yard for about $25 bucks each. They produce plenty of power at idle vs some of the high output alts that don’t produce much at idle. Another advantage is that heat build up is spread out with mutable alts. Heat cuts down on the output of any alt and it can be a considerable amount. So one high output alt hot at idle may not even come close to putting out as much as two stock 140 amp one wire units.
