My truck battery loses voltage and won't start,when i don't start it for 3 days.
If i drive it everyday, it starts up with no problem.

I also notice when i signal with the emergency brake pulled up with the key in the igniton to the last click before starting. The brake light on the instrument cluster starts to flicker also.

Anyone with the same problem or have any idea of what's cause my battery to drain, or know what is causing my signal light to interfer with the emergency brake light?

Pls lmk (Thanks)
