New to RV
I just bought a new, to me, 2010 Sierra 355QBQ 5th wheel, and love it. Everything works great.. but.. the monitor guage, for the holding tanks and battery, does not work. (well I think it doesn't) When I push any of the buttons, only the bottom red lights comes on, just for a second. I know the holding tank are empty, but if I am pluged in w/ shore power, shouldn't the battery guage say Full??
What should I check first?
