I did some work on the truck yesterday, and partway through the work I noticed that the heater fan was running very slowly, while the truck was shut down. I figured that it was odd and unplugged the fan. Took the truck for a test drive at the end of the day and everything worked great. I went out to drive it again this morning and the battery was dead. DEAD dead. Like, so dead that the solenoid wouldn't click and the lights wouldn't come on at all. I junpstarted it and drove it around a bit, went to get gas and it wouldn't start after I had put gas in it. A friend came to jump it and I went for a 20 minuted drive to try to get the battery charged up. When I left the house the battery was reading about 11.5 volts when the truck was idling, when I got back it was 12.5, so it looks like the battery was charging on the drive. I doublechecked all of my work, nothing that I worked on yesterday is drawing power when the truck is shut down. If I disconnect the battery it stays at the same voltage, if I connect the battery cable I can see the voltage go down really slowly, about 3/1000 of a volt per second. If I run the truck at 2000rpm I can see the battery charging fairly fast, about .5 volts every minute. It's on an external trickle charger now to see if it will take a full charge. The electrical system has never given me any problems on this truck, but I know that the ignition switch is worn. Could it have finally eaten it and that'w what's causing this, or this going to be a bigger problem that will take a while lot of tracing of wires? Help! I really want to get out and enjoy my truck, but every time I get something fixed something else goes wrong the very next damn day! Sorry for the long post, I just wanted to give all the relevant info.
