Canyon Trail 2003 5th wheel For some reason the overhead lights (3) and fan in bedroom and bath stopped working. The one light over bed works and also the outlets work. The GFI outlet by sink is not tripped. Also, my Jupiter 3000 watt inverter sounds an alarm ( about 15 seconds) every morning at 8 AM since light problem above. The 6 gulf cart batteries all test ok individually and as 12 volt in aggregate. Any ideas would be appreciated. Thanks in advance
