Any suggestions appreciated. I need help I went to the car wash a couple days ago and as I got home all my accessory lights came on. Everything was fine I just thought it got wet and would turn off after it dried. But anyway the next day went to work everything was still fine except the lights were still on. So than I drove home from work got home shut it off and tried starting it again and no power so I boosted it and was running again drove it around the block than let it run for a couple minutes. Than it died and I had no power inside my truck no deck nothing and only headlights work and now I can't figure out what it is. Checked all fuses all wires all connections and all grounds anybody think of something it could be?

 

Sounds to me like you washed the alternator to well!

I would look at your fusible links.If you caused any of them to open

The battery voltage is below the critical level for the computer so it shut down to protect it.
