Ultrasport house batteries won't recharge
I have a Damon 2000 Ultrasport, 38'. Starting last year, after plugging into 50 amp or 30 amp, the house batteries would drain. It is my understanding that the inverter should be charging the batteries as they are used. Whenever I plug and let the coach sit the batteries are now draining. I have no charge left. This just started. Had new batteries in chassis and house put in. I had the coach checked and some parts replaced in the electrical system with no luck fixing the problem.
Has anyone seen this and what was done to fix it?
