We have a 2007 georgetown 350dsse, last week I installed two six volt batteries because the last two 12 volt kept going dead, after installation everything worked great, three days later we were going to go camping and the batteries were dead. I pluged into shore power (15)amp nothing. I started the motorhome they began charging. Got to the campground pluged into 50amp also began charging, during the night, the solonoid began clicking off and on. when we got home I checked the voltage 12.9 in two minutes it drained to 5.9. The next morning 3.2 when I disconnected the teminals it was 7.66. Forest River says it's the battery control center $349.00, just hate to spend that if it's not the problem. Any suggestions?
