Recently replaced rear cameras from Revcam on a Bessacarr 496 - all were working perfectly - after a week went to use MH this morning & no power on Rearview Monitor
- searched high & low for possible cause and checked all connections etc. I was just about to order a new monitor! I had replaced the Leisure Batteries a few days earlier & had not expected them to have affected the monitor - reset electrical control unit in Habitation of MH and monitor started working correctly (totally unexpected) - Hope this helps someone else and avoids a costly dealer repair !
