On my coach, the start boost relay is located on the back-side of the 12 volt Distribution Circuit Board. This board is located on the back wall behind the Inverter in the rear bay, passenger side. The start boost relay cannot be seen from the front side of the circuit board, however you can feel it back there. Rook
When you get a chance to dance, or sit this one out......I hope you DANCE!
