marte6 Report post Posted July 19, 2015 When I started my generator when there was a power outage in the RV park, I got a hammering sound and the there was no indication on the control system that there was power to the coach. Would that be the inverter or the transfer switch or what? Shutting off generator and waiting a while and starting it again seemed to clear it up. But it felt on the floor of the coach like it was coming apart. Share this post Link to post Share on other sites
