Just purcased a 1971 31 ft
sovereign,all
12 volt systems work rplaced the
12 volt battery, but when I plug shore power in I loose all
12 volt lights and fans, I have 12.6 at the battery but no power through the inverter. the inverter 120 side has 126.5 volts and nothing on the 12 volt side. There is a yellow wire that I believe should have 12 volts but does not, I have traced it as far as possible and connot find the end of it, does any ony know where the yellow wire goes or what could be the problem. Thanks Steve
