I'm on the edge of cancelling a camping trip because I can't figure out why I'm not getting DC power to anything in my 2009 Aliner Classic.. Shore power is fine. i did install a new frig vent fan, and unfortunately did not check DC power before that. Everything was fine in late June the last time we used the camper. The frig and fan work fine on shore power but, like everything else, not on DC. I traced good DC power at only 12.1 V at the battery at the last connection before the power center. WF-8735. Testing inside the PC? I don't know what to connect the + of my voltage tester to. There is a neutral bar and a ground bar behind the cover.?
