I just recently bought a Toyota New Horizon over the weekend. It's in pretty fair condition for the age (1987) minimal rust, engine runs strong, one leak repaired awhile ago with no squishiness around where it happened. The problem is the electrical system in the back. Previous owner said he's not sure what happened to everything (it worked for his last trip, but not when I was checking it out) but I figured it was just that the house battery was dead. When he plugged it in, the pump and outlets worked. So I bought it and drove it home for about 3 hours. I figured that'd be enough to charge the battery to full if not near full, but I go to the back, hit the power panel and it lights up, but it shows the battery as just one dot fully charged! I looked at the deep cycle battery and it's not the original but it's not new either. The leads on it are fairly corroded...
Are three hours not enough to charge a house battery? How long would it take to charge it? (if it were plugged in or if you were driving..)
How would you tackle this problem..?
I'm sure I could just google this but I'd love to hear about it from people with experience with Toyotas...
