He said the batteries ended up being connected wrong. I am having the same issue on a truck I just got.
Have you by any chance figured it out? i am having the same issue for about 5-6 months! I’ve changed the batteries and cleaned the connections on started and battery connections looked healthy! Anything you can tell me on how you fixed the problem?
