Randy,
I think that your cord reel is feed from one of the circuit breakers next to the shore power breaker box. However, the only problems that I have encountered with an inoperative shore power reel on your vintage coach was either from a bad switch or a bad connection in the wire from the reel connector box and the switch. Beaver cut that wire between the reel and the switch for easier installation and their reconnection point is prone to corrosion especially in any coach that has been driven on a salted winter road.
