Hi gents. My battery light is only coming on at start up first thing in the morning after sitting overnight. At no other time........I got new OEM cables in 2018. I went ahead and replaced the battery and still the same problem. Concurrently I am having an issue with my reverse lights apparently coming on randomly, since my Alpine Applecarplay system thinks it’s on reverse while driving sometimes.

I am thinking the problem here is something that’s draining the battery. Could a faulty brake switch or reverse switch be draining my battery overnight?

any help appreciated
