Coming home on a hot day last month in our 2006 Tiffin Allegro Bay 37QDB we experienced an electrical problem. The following items are not working: Electric Window on the Driver's Side, Backup Camera, Levelers, Slides, Dash A/C, Electric Mirrors. We have the electrical diagram in the owner's manual, but it is on 8 1/2 x 11 paper and the pages do not align. Plus there is no diagram concerning the dash. We have determined that there is no power going to charging battery boost solenoid. We have installed a new solenoid and this did not help. Does anyone have any suggestions?
