Ok. i just got my first winch the other day. I noticed that the voltage drops to 9 when in use, i know thats normal if i dont have an upgraded alternator or dual batterys but i was wondering if there was a rebuild kit or something like that out there that will boost the stock alternators amp instead of buy a whole new unit. And if so how high of amps should i have? I've also heard of some kind of idle controle system that when you flip a switch it will keep your engines revs higher while you use high electrical equipment, kind of like they have in patrol cars or tow trucks, but for the life of me i cant remember what it was called. Any ideas?
