## Discrepancy

NOTED A CLICKING ACCOMPANIED BY AMMETER INDICATING A HEAVY DISCHARGE.  PROBLEM ISOLATED TO A CIRCUIT BREAKER THAT WASN`T TRIPPING THE INDICATOR BUTTON AND WAS WORKING AS AN AUTO RESET BREAKER.  A SHORT WAS LOCATED WITHIN THE ALREADY PLACARDED " INOP" ADF.  THE OWNER COMMENTED HE THOUGHT THE ISSUE WAS THE NORMAL OPS FOR THE PULSELIGHT SYSTEM.
