what year is the truck, mileage, and what is the history on the battery?ShipFixer wrote:Luckily I live next to a hotel and caught a cab to work. Tried to start it this morning and it immediately and completely died electrically. There's a tiny bit of power going to the seat belt light but that's it. No interior lights or anything.
I managed to reset whatever it was by disconnecting and reconnecting the battery after work. Interior lights came on, but as soon as I tried to turn the key it died again. So I'm thinking it's a relay somewhere.
Going to go troubleshooting and poke at relays in particular, but just curious to know if anyone has an idea what it might be. Going to try to clean and reconnect the battery terminals (again) but since they're pretty well coated in dieletric grease I don't think that's it this time.
You can't diagnose based on that... Only under load can the number be reliable... Defective year old batteries happen sometimes... Besides if it's only a year old then it's still under warranty and may even be free replacement at this stage... Let the vendor/retailer check it out.ShipFixer wrote:Battery has 12.6V, that's not it...

Anyway, it wasn't the battery. It was the terminal again. Sanded to bright metal, cinched down, regreased...
The battery holder had worked loose so I'm thinking maybe it let the terminal wiggle and allow dielectric grease in between. It was a little too easy to loosen the terminals. Since I just went through this a little while ago I was pretty sure that couldn't be it. But...whatever, it works again...
