I’ve made a start on getting the auxilliary battery system and fuse box installed. Using two Odyssey batteries, one for the vehicle electrics and the second as an auxiliary battery to power the fridge, winch, lighting etc…

The two batteries are isolated/connected together via a solenoid that is activated at the moment when the ignition is turned on. At some point I’ll change it so that it’s activated when the oil pressure light goes out with an override to allow it to be connected as a “jump start” battery should the main battery lose charge for any reason.

The auxiliary fuse box is a modular type allowing the inclusion of relays and fuses in each section, according to our eventual needs. It sits quite nicely behind the passenger’s seat and should make it easy to provide power to both the rear and the front of the vehicle.
