[QUOTE="froggy, post: 130280, member: 3485"] I run this new type of relay and i'm not totally convinced by it. I have issues with the relay not switching off even with the ignition off. The feed is from the start battery / alternator into the relay and then from the relay to the leisure battery. But because the relay will always see a voltage above the cut off voltage of the relay then it will always be energised and trying to charge the leisure battery until the start battery voltage drops and then the relay will cut out, but then with no load the start battery voltage picks back up and energises relay etc etc causing the relay to chatter. This is what happened to me at bus types and in the end i pulled the in-line fuse from the start battery to the relay, now thinking of re-wiring it via a old type relay that so that it requires an ignition input to turn the relay on. Anyone got any other ideas? [/QUOTE]
