Update. I didn't find the problem, but the last couple cold mornings (coldest), the truck started fine and seemed to have full power.

A couple things that I did when I started looking into the problem.

Replaced a blown cigarette lighter fuse.

There was two black wires coming off the red battery cover under the hood. One fused and the other one didn't have a fuse that I could see. I think one or both (not sure) go to the trailer brake control under the dash. I removed both wires from the connection and check if the drain went away, but it didn't, so I connected it back up. I don't remember exactly when, but I noticed the trailer brake light was coming on one day when I started the truck. Then it was dimmer and eventually went out. I never seen this light on since I have owned the truck (around three months) I did not install this, nor did I use it or know how it's supposed to work.

I have not checked for the drain off the battery with the meter. I don't know if I should touch anything. :?:

So I'm wondering what I did or what the problem actually was. :?

I wonder why the battery is not draining down if you still have the power drain.

I said I have not checked for the drain yet. I will give it another couple days to see how it's doing (we're have a cold spell with 10 degree mornings). I will will eventually check it.

I did remember one other thing I did when testing things out (I might have mentioned this, not sure). I disconnected the alternator and checked for the drain (drain was still there).

I guess I read it wrong.
