DOCKC Report post Posted December 30, 2013 Good morning. This is my FIRST post on FMCA forum. I have a 2005 Beaver Monterey diesel. Prior to my purchase, all new house batteries and an inverter were installed. It had been very cold in the single digits. I did not plug the coach in for a week. Sometime after that, the batteries are not charging -- thus, no lights except when under shore power. I checked the batteries and they are from 3 to 5 volts. All of the fuses are working. If I turn on the generator, the lights work well. I DO NOT GET IT. Any help out there. Doc KC Share this post Link to post Share on other sites
