Re: Battery Drain
The BCM directly controls all the interior lights to prevent battery drain. Everything should be completely shutoff by the 15 minute mark. By 20 minutes the BCM should be asleep. If you have not done any modifications on the truck since or recently before this issue has started-
Take your **** down to a couple different parts stores and have them test your battery. Note I said couple. My past experiences have shown you dont know if their equipment is working properly or if the employee knows what the hell they are doing. I'm betting your battery is ****.
I had a bad cell or two on my optima. I had that battery tested 3 different times at my usual place, tested good every time. Second store the 4th time said my battery was **** right away. I could go for weeks, hours, days between issues. Completely ****ing random. Go in a store for 45 minutes and have a dead battery, then the damn thing would be fine for days or weeks again.
I'd almost be willing to be you a six-pack thats your issue. Dont buy a yellow top optima, they're not built like they used to be. I've had zero issues w/ the newer red tops.
