Question for you vets. I have an old Beaver Contessa (1990). I've had it for many years and never a (major) issue. I just installed (2) new battery's and I recently took a 250 mile trip with zero prob...
Thanks very much. Starting to make sense. After all these years, this is the first time I’ve been hooked to 50 amp for extended periods. The coach has a disconnect on the coach battery most likely for that reason. It’s fully charged so I’ll disconnect that 1 battery and try that. This coach has just 2 very large deep cycle batteries. Never had the issue when stored because from what you guys have said, that’s when solar charges one which keeps the other charged. Thanks again
