## Discrepancy

(CAN) DURING A DAILY INSPECTION, IT WAS NOTED THAT THE TAIL LOGO LIGHTS WOULD NOT ILLUMINATE.  INVESTIGATION OF THE SYS FOUND BOTH BULBS SERVICEABLE WITH NO POWER AT THE LIGHT ASSEMBLIES.  FURTHER INVESTIGATION REVEALED A CHAFED WIRE THRU A BULKHEAD GROMMET LOCATED IN THE LT NACELLE.  WIRING WAS REPAIRED IAW STANDARD PRACTICES AND LIGHT STILL WOULD NOT OPERATE.  FURTHER TROUBLESHOOTING IDENTIFIED THAT THE CIRCUIT BREAKER, ALTHOUGH CLOSED HAD HIGH INTERNAL RESISTANCE.  CB REPLACED AND LIGHTS CHECKED SERVICEABLE IAW 33.  ALL WORK WAS PERFORMED IAW AMM.
