Hello! I'm hoping you all can help me. I have a 2009 Winnebago View. About 7 months ago my coach batteries appeared unable to completely charge (based on the reading on the house instrument panel and reduction in time between charges). The batteries were old so I had them replaced and all was well for a month or two, then I noticed the same thing happening. I was only seeing about 2/3 charged on the house instrument panel no matter how long I plugged in, drove or ran the generator. Eventually that dropped to the point that I was only seeing 1 red light or at the most 1/3 charged. An RV shop (the same one that supposedly checked my electrical system when they installed new batteries) theorized that the battery mode solenoid under the passenger seat might not be working, preventing the coach batteries from charging. I had the solenoid replaced, no improvement. Recently my new mechanic suggested the batteries have probably been ruined due to being completely drained too long, so we just replaced the batteries again and there's still no improvement. The batteries are fully charged. When the RV is plugged into 120v shore power everything works perfectly and the house instrument panel shows full charge. On 12 v power the house instrument panel shows one light (basically no charge). I'm getting enough power to turn on lights but they flicker if I turn on the water pump and the pump is weak, so the house is only getting a little bit of power. I could understand if only one appliance was affected or if there was no 12V power at all, but what's causing it to be so weak? I have confirmed the battery disconnect switch is not flipped -power is on and the light on the switch is green. However the Tri-Metric meter next to the battery compartment is completely dark and I can't get it to turn on. That meter was always on prior to this problem. Any ideas? I tried flipping the breakers on the 110v side of the converter but am not sure what else to try. Thanks!
