Was doing some work on the truck new years eve. I had the dome lights on pretty much all day, and I wasn't thinking so when I went to start it that night and it was pretty slow, I figured it out. Started, drove to a buddies, when it wouldn't start the next morning.

My alarm doesn't work that well either. I'm pretty sure it's the original battery too.

But when I put the MM on it it read 12.6 volts. Something doesn't make sense here. I put the key in and nothing comes on at all. Could the voltage be dropping that much?

It starts off a jump so I'm pretty sure it's the battery. I removed my power wire from the battery NYE, but I've done it many times before and never a problem, so I'm ruling out wiring problems.

Could my battery just be f-bombed from leaving the lights on all day? It also won't take a charge, as I drove it for about an hour and it wouldn't restart on it's own when I brought it home.
