## Discrepancy

(CAN) WIRE PROVIDES POWER TO THE BEACON LIGHT ON THE VERTICAL SECTION.  WIRE SECTION BETWEEN SWITCH AND CONNECTOR HAD BEEN REPAIRED WITH A BUTT CONNECTOR.  WIRE LENGTH IS ABOUT 7".  WIRE OVERHEATED AND CHARRED THE INSULATION.  WIRING IS ORIGINAL WITH OVER 7,000 HRS AND 40 YEARS OLD. IT IS UNKNOWN IF THE SPADE CONNECTOR TO THE SWITCH IS ORIGINAL OR HAS BEEN REPLACED. THE SECTION OF WIRE TO THE CONNECTOR TERMINAL IS ORIGINAL.  WIRE BEYOND THE CONNECTOR APPEARS TO BE SERVICEABLE.
