Troubleshoot your DC battery and charging system.

Well that makes sense. Just purchased this unit a week and a half ago and the owner said it set out in the back yard for the last 6 months in the Florida sun. Also said the grandkids were in and out of it so lights were properly used off the battery.
Going to look at that today and will let y’all know what I find.
