Folks,
I have recently acquired a 78 camper. It seems to slowly drain the battery over a period of a few weeks. I only have the ignition battery installed. The aux. battery is not in place with just the bare terminal connectors lying on the battery tray area.
My question is this: could the aux. battery cables (if not hooked up to a battery) cause the main battery to slowly drain? I know there is a switch for the dual battery. I believe mine is off. The only electrical thing that is not original is the stereo. I believe this may be the problem if it is not the aux. battery. Other than that, I would suspect the ignition switch next. The van only has 80k original miles on it. So I am not inclined to think that the ignition may be worn out.
Any thoughts?
Thanks,
Matt
