Just starting to wire up my dual batteries so I can get my full sound system installed. I'm using a Smart Battery Isolator which are pretty much the best isolators available for ATV dual batteries.
Hard to find large & high quality diagrams, so I usually make my own on PC & save for printouts anytime I need them. Hope it helps someone using the Smart Battery Isolators!

I'm using the Aopec Smart Battery Isolator but identical isolator is also sold under the QuadBoss, KeyLine Chargers, TrueAM UTV, PowerTech, VSR & tons of other brand names.
