What is your alternator putting out for voltage? how about the batteries, one or two batteries, 12 or 24V, do they keep a charge for a week.
Actually, none of that matters much, the alternator is connected directly to the battery usually. You need to find what's drawing too much amperage that goes through the switch. Maybe a fuse that's too big on a circuit that's overloaded, or new accessories added?
