[QUOTE="olympic, post: 16509795, member: 168598"] 1. What alternator did you choose, price, and why. [color=#ff0000]Bought a Mechman in early 2016 for $450. J2 and KMJ didn't exist back then so the top options were Mechman and Nations. I chose Mechman due to their reputation and lower price.[/color] 2. At what point do you need a 130, 185, 200, or 240A? [color=#ff0000]Mine is 170A and it holds up OK with dual GT fuel pumps, heat exchanger fans and a sound system.[/color] 3. Did you do the big 3? What kit did you use and was there mods needed (splicing, etc.) [color=#ff0000]Yes, I made my own with 0 gauge OFC cable.
