Ahhhh, one thing I didn't see anyone mention. Disconnect the battery to let the system reset? Worth a try...

Try this if you don't have a schematic or have experience in troubleshooting electrical systems. Buy a simple volt meter. Turn dial to12vdc. Use aligator clip to attach black probe to battery negative terminal. Touch red probe pointy end to battery positive terminal. You should read somewhere around 12 to 12.xx volts DC. Now you just follow the wires from the positive terminal point by point leavi.g the black probe in place until you find a place where 12vdc goes in but nothing comes out. Simple yes but this is the basic process for electrical troubleshooting. Having a schematic is like a road map of where the electricity can travel and understanding one is best but you can still get there the hard way with the advi e above. Good Luck!

Sorry. Maybe I was reading to fast, but what about the circuit breaker? Are you sure it wasn't tripped? It's located on the side of the battery tray, in a real fk'd up spot. If the button's sticking out, just push it back in. Happens occasionally when system's been overheated. Otherwise, could also be voltage reg. Lota good advice, tho. You'll track it down!
