## Discrepancy

(CAN) AC WAS SNAGGED WITH GEN LIGHT NOT ILLUMINATING WITH BATTERY AND GENERATOR SWITCHES ON. DURING TROUBLESHOOTING IT WAS FOUND THAT WHERE  ALTERNATOR CONTROL AND BATTERY WIRES PASS THROUGH GROMMET OF ENGINE BAFFLE, WIRES HAD CHAFFED THROUGH PLASTIC INSULATOR OF WIRE. WEAR WAS CAUSED BY CHAFFING OF GROMMET, WIRES. SNAG WAS CONFIRMED WHEN ONE OF CONTROL WIRES AT ALTERNATOR PLUG WAS FOUND BROKEN AT SPADE TERMINAL. ALTHOUGH UNRELATED TO SNAG, WIRE CHAFING WAS SECOND AC FOUND WITH SIMILAR WIRE DAMAGE. WIRES WERE REPAIRED AND AIRCRAFT RELEASED. MFG HAS BEEN ADVISED.
