Running stereo/ac& interior lights off AUX batt

[Rosie Junior Member Find all posts View Profile Close Rosie]

Hey guys, got a petrol 120 series with a simple red arc smart solenoid dual battery system. Right now I have my fridge, work light and rear power running off the Aux batt but I would also like to run the stereo/accessories circuit and interior lights from the 2nd battery as well.

Has anyone done this? Got any suggestions on wiring it up?

Thanks, Rosie

Relatively easy to do. Simply locate the stereo power cable that feeds the normal 12v power (ie accessory power) and run a relay with a switch through to the aux battery. Use the relay to stop power going back to your other accessories. Works a treat and saves you needing to have the key on aux/ign while at camp. The same could be applied to your internal lamps in theory as well, but I've only ever bothered with the stereo.
