Weird goings on

[UnclJim]

Been having an issue for a couple weeks now.
Turn truck off and I get a pop in speakers if radio isnt' shut off. Sometimes the truck will go dead upon shutting off, open close reopen door and truck is alive again. On a rare occassion truck will be dead in the morning i will need to open it with key and after a minute or so it come alive and alarm goes off. Also I will need to reset climate pre settings, as well as turn fogs back on after most shut offs . Also surround sound will be turned to off.
Truck still has driver presets as well as remembers my cell phone. Any ideas?

Maybe get a new battery. Or have yours tested. Or just get a new, better one.

Well, people like me on the app can't see signatures so that doesn't do any good.

thats my thinking but i see no leak going to look under seat to see if it damp back there. Ill recheck seal at 3rd brake light as well.

Have you tried the old battery disconnect trickeration yet?

Bad ground, if the battery is good.

I see in your sig that you have added a lot of electrical goodies, any chance your problem coincided with the the timing of one of those? Outside if that, I would suggest checking for loose connections at the fuse box in the engine compartment, as well as the ground connections at the frame.

everything runs independent of the electrical system of the truck.

It ended up being the ground connection there was an odd upward slant to the battery post I had to get small lead shims to put in at top of terminal connection to keep terminal from walking up.
Thanks all for the input!!

Yep. Bad grounds are common and troublesome.
