So I'm trying to figure out which of the Power Master 140 amp alternators to go with for my truggy. It'll be set up with dual Optima's on the Hell Roaring dual battery kit for the winch, lights etc. Do I need/want a 1 wire or 3 wire? Whats the difference? Can someone explain the differences between the different cases? GM 10si, GM CS130, GM CS130D etc? Which case do I have? On the Summit website theres about 20 different Powermaster GM 140amp alternators....Which one do I want? This is the one I think I want- http://store.summitracing.com/defau...earchinresults=false&N=0&target=egnsearch.asp Will this thing bolt up to my brackets? I'm totally ignorant as far as alternators and electrical stuff goes, so pardon all the questions. I've been researching and reading about this stuff so much my head hurts. Getting the truck ready for Blazer Fest next month, but mostly for Blazer Bash in Moab. I'll be damned if an alternator or some other stupid component ruins my fun when I'm 900 miles from home.
