[QUOTE="pgtips, post: 630213, member: 13573"] Also something I have found and solved recently on VSR (voltage sensing relay) if you have different batteries, like AGM LB and lead acid MB there can be cross over as the LB might hold the relay open (I charge from LB side on shore power and if I disconnected my MB the relay held open creating power on ign circuit.) Also AGM charges different but without getting into it there is a fix. Feed the earth wire to the VSR via a 4 (or 5 pin if thats all you've got) relay. Make the earth feed relay ign switched to cut earth (turn off relay) when parked up and ign off. This way the lower AGM LB voltage won't hold open the relay. I hope that made sense. Graham is right though, 50A on each side, as close to battery as possible. [/QUOTE]
