Hi new to this forum and Winnies- and I apologize in advance if this question has been answered on this forum before, but I can't find in the search feature here. My house batteries are one year old and fully charged- I can't find any blown 12V fuses in Parallax power center and have tried switching Auxiliary Battery Switch near entrance on and off numerous times. All 12V items work with shore power plugged in. Does anybody know if there is a hidden fuse between switch and power center somewhere that I'm missing to check? Any help deeply appreciated have trip planned starting tomorrow!
