I've searched this issue and don't have a full grasp yet on what I can do to fix it. I own a 2003 Starcraft 1701L. The lights and heater lose power and don't work. I replaced fuses, they worked fine then shut down again. I removed the 15 amp fuse from the converter and the red light for the amp socket came on then I put it back in and it the lights and heater were fine all night. In the morning the power to the lights and heater went out again. Took out fuse, the red light did not come on this time, replaced it and the heater and interior lights didn't work. Help!
