Ya'll,
I've been reading the parasitic draw and other dead battery posts. I'm hitting a bit of a dead end. I'm going to list all the info I can about the problem. Any advice you have on solutions to similar problems would be greatly appreciated. I'll put in more details as I think of them.
1. 2018 1500 Big Horn 5.7 4x4 and trailer package.90,500 miles- no warrantees.
2. When shut off, the truck will drain it's battery (except when its at the dealership of course)
3. The instrument cluster back light will stay on. This is not a consistent symptom, but it's happening more often.
4. There is a high pitch whine coming from somewhere between the transmission and the engine. Link to a video of the noise.
5. Pulling fuse- F52, a 5amp, related to the battery sensor stops both the whine and the cluster back light. Can I drive without the fuse and not hurt the truck?
6. Putting the fuse back in starts the whine and the back light.
7. It's throwing a P1DCA code and for a time, a B0007 code(not sure if this one is still there). My OBD2 sensor kicked the bucket and it's tool late to go to O'reilly's.
7b. P1CDA-
Thanks so much for any help you can provide.
