Re: Found a Diode ????
Its a diode added to allow the volt meter or perhaps ammeter to run without providing a way to drain both batteries ( I don't know I'm just guessing). Whichever battery is 'on' that diode allows whatever equipment to function and not drain both batteries. You're right, it's small, therefore small equipment. I have done this many many times. Stereos are one thing people like to have on all night, along with anchor lights and fans in the cabin. I could be completely wrong here of course, but perhaps whatever was controlled by the diode is no longer there. Maybe it ran one of those vibrating bed things the previous owner stole from a motel once and instead of coin box for quarters it has the diode now.
