<strong>Yahoo Message Number: 93662</strong>After a bitter cold snap, I went to check on my coach (2005 Magna 630, a relatively new coach for me) and noticed all 12v house power was out. I still had 110v from my 50 amp shore connection, but the 12v systems (lights, SilverLeaf panel, etc) were out. I was able to start the coach, and the alternator powered up the 12v house systems fine....
