Slow battery drain question
Been noticing a few extra rotations to start the truck in the morning. Charged the battery, checked with a meter 12.5, 4 hours later 11.9. Pulled the fuse from the main roof light power wire. 4 hours later 12.5. So it must be the lights but how. Poor ground? I`m not much of an electrician.

How old is the battery? Might not be a bad idea to upgrade especially since you have the winch now unless you already have. I can say that with my optima and CS130d alt I can do a pull at idle with the ac on and only drop about .5v.

how do you have the roof lights hooked up? Since when pulling the fuse, it stopped the drain, so it has to be how they are wired. The ground would really not cause a parasitic drain. That would really only cause problem when they are being used.

This morning it showed 11.92, wouldnt even turn over. Battery was less than 1 year old autocraft silver. Pulled it out and brought back. They said it needed a charge, I said I want a new one, wait, I want to upgrade to the autocraft gold. They agreed to it. Cleaned up all the connections during install. Will monitor through the day. Is it possible the big 3 upgrade could cause a drain some how?

Update, new install was 12.40 at 1pm at 2:15 it was at 12.40, 4:00 it was 12.39 volts and 6 pm it was 12.38. Feel good that it was the battery seeing it only dropped 2hundreths in 5 hours

I dont see how the big 3 could cause a drain unless you did it wrong, but if there was no sparks or fire when running LOL
That is crazy that it would not even turn over at 11.92v.. That is definitely a bad battery, LOL at the place saying it needed a charge.
