## Discrepancy

(CAN) ON APPROACH IHAD A DUAL INVERTER FAILURE. IT WAS CONFIRMED THAT THE 26 VAC WIRE WAS SHUTTING OFF THE INVERTERS DUE TO INCREASED RESISTANCE. WIRES X26A20V AND X27A20V (26 VAC FEED LINES) WERE FOUND CHAFFED BEHIND THE CIRCUIT BREAKER PANEL. ALSO FOUND WIRE X25A20V NICKED IN THE SAME SPOT. THESE WIRES WERE REPLACED AND RE-SECURED TO PREVENT FURTHER CHAFING. THE SYSTEM WAS CHECKED SERVICEABLE.
