Just though I would quote real quick I am very amused that you think the box on # 4 contains batteries, not the case!! the pic that said battery is all that we have, it is the battery for everything like the lights, spiel and etc. How ever though the low water system and governers for the compressor are powered by solar panels!! yes thats right solar panels and the panels are located on top of the cab roof next to the door hatch so you cant see them, by the way thank you DL Roundhouse for not firing me yet for how much info. I give out to ya guys!! LOL
Right. The low water alarm system doesn't need batteries because it's solar powered. At night time, they don't have to worry about low water situations, right?
You might want to tell that to the guy who designed and installed the low water alarms. He's on the this board frequently.
