## Discrepancy

FUNCTION TESTED ELT SYSTEM DURING 100-HOUR INSPECTION.  ELT COULD NOT BE ACTIVATED BY REMOTE SWITCH OR COPILOT'S  INSTRUMENT PANEL.  INSTALLED SERVICEABLE ELT AND OPERATED NORMALLY, HOWEVER, RED LAMP ON REMOTE SWITCH DID NOT ILLUMINATE.  INSTALLED NEW SWITCH AND ALL FUNCTIONS CHECKED NORMAL.  MASTER SWITCH ON ORIGINAL ELT AND THE G-SWITCH BOTH SEEMED TO OPERATE CORRECTLY WITH UNIT REMOVED FROM AIRCRAFT.  ELT MODEL, 3000-11.  SWITCH, P/N 2019-10.
