Troubleshooting Low Voltage:
 

Hi guys!! I have a 2005 Dodge 1500 Ram. I had a bunch of codes come up all at once. First it was P0562- Voltage(engine side) Too low. We decided it was maybe a bad battery so we replaced it, but then the other codes came up all at once. They are: P0700-Transmission Control System Malfunction: P0891-Transmission Relay: P0480-Cooling Fan Control Circuit Malfunction. I havn't had any trouble with the truck prior. But the funny thing is that the day before when the truck was shut off, the fan kept running and ran the battery down, that is why we thought it was the battery causing it. We are mechanically inclined and fix everything ourselves but I think its a far bigger problem..Any ideas??

Thanks
