hello, i'm moving from Massachusetts to California, i just bought an old mini-cruiser to make the trip in. It's old but it's in great shape. I haven't had the chance to plug it in yet, but i noticed it has 12v lights inside. They don't turn on, and i can't find a manual anywhere. It has a new battery, but it also has a multi-battery isolator, that looks like it's been unhooked, and no second battery. does anyone know if these are supposed to run w/o plugging in? or where I can find a manual or users guide? it's an 85 so I haven't had much luck... also any tips on good places to stay, I'm leaving in October and i plan on taking my time. thanks.
