I just put a 200 amp alt in my suburban which had a stock 105 in it before. my queztion is my stock alt idled at a higher voltage? I had my alternatorrebuilt so everything is the same as stock(pulley). As soon as i hwithit the gas my votage jumps up. Ive done the big 3 with 4ga but i left the stock wires in place. My question is why does my battery still die on me? Its a deep cycle marine batt(105 amp hr). Only thing that makes sense is i only drive about 5-10 minutes one way to work. Imrunning a brz1200.1 wired at 1ohm and a r.f.300.4 Any help would be appreciated. Thanks!
i tryed to check it with my dmm but it took a shit on me so ill have to get a new one. i took the batt to advance auto and they charged it so idk. its not very old maybe 7 or 8 months old it was my reserve battery outta my boat and i never had to use it so maybe ill just buy me a new one.
ok thanks that answers my question . I was told that i would get more amperage at idle from a higher output alt so i was a little confused, but i kinda figured that with the bigger windings, so i just wanted to make sure before i switched to a smaller pulley
