June 28, 201114 yr On one battery you are in the rated range @ 2220, might want a second when you step up the output. As for your alternator, that's not going to keep up.
June 28, 201114 yr I've got a 5100r and a 1200 on a 60 amp alt, with a sundown 1500 and my alt can't keep up. No way yours will with that much power. Lower your power levels 'till you get more power available.
June 28, 201114 yr I'd be surprised if you're not having major voltage issues already running 2k+ with all stock electrical. You definitely need to get some in there.
