you could try to power the DC and the AC parts of the coach off at the same time ,leave it off for 10 seconds and power the AC side up first then the DC. If the inverter has failed you could just splice the AC feed in and out together . There is also a small breaker on the face of the inverter , I think its 10 amps. Not sure where your inverter is but ours is on the top shelf of the basement pass though .
