[QUOTE="keep_hope_alive, post: 7401141, member: 576029"] this should be a new thread. please start one. beatnbronco: multiple batteries will feed off each other and if not equal, the weaker one will drag the others down. if they are not sealed AGM batteries - check the water levels. your wiring sounds like there is a lot going on. draw diagrams - as clearly as possible, to describe power and ground. yes, a 500A isolator would allow two batteries to land on the terminal. but the isolator isn't really a solution since the batteries shouldn't drain if everything is ok. batteries need to be charged and they should rest between 12.5-13 VDC. lower than that and they aren't charged. more rugs of 0 awg will just lower resistance and shouldn't have adverse affects if properly done. if any insulation is compromised or a slight short has developed, the batteries will drain. in your diagram, include fuses. you should have a fuse on every power wire that leaves the positive terminal of a battery (except the wire that parallels the aux batteries).
