2004 Pace Arrow 36B DC power
2 questions: I am not showing any power on the digital display for main power but motorhome will start. Aux power reads fine. Due to this issue I am getting no read out on grey, black, or fresh water indicator lights. Is this a fuse issue and if so, do you happen to know which one. Or where it may be located. Second question: power disconnect switches, should I push the switch up or down to allow charging?
