OK, check this out. I stopped working on the truck Saturday at about 3:00. I left the key turned to accessory and a bunch of things turned on. Even though the battery was charged I left the charger on it. Nothing continued to happen Saturday and Sunday, I got home from my night job at about 11:00pm Sunday night, nothing was happening. At 7:00 this (Monday) morning I come out of the house to go to work. The truck is buzzing and the lights are on!

I run over to it and turn the key to off and shut of the lights. The buzzing stops and the lights go out. Just for fun I turn the key forward and the engine turns over. I'll try it again tonight but this is very odd.
