    Not sure if the van is new to you or if you've used it before. Is there a switch on the controle pannel that says"towing" and "onsite" or something like that ? it should in the on site position .

    the charge relay is NORMALLY as close to the battery as possible.

    it should kick in when the engine starts, not just ignition on.

    needs two people ......locate ANY relay near the battery and hold a finger on it while a mate startes the engine...you should feel it click.
    any that doesnt should be treated with suspicion.

    the easiest way is to disconnect the relays in turn, if more than one, and see if one kills the hab power. .

    usually a small black or dark red box, could be aluminium but usually plastic, about 30mm x 30mm x 40mm with the wires exiting the bottom via a moulded plug.

    They can be many colours, mainly black, sometimes yellow/blue/green. the smaller ones are about 25mm square usualy plastic cover with four wires coming out of one side or pushed flush into a fuse box etc.
