## Discrepancy

LT AND RT ENGINE THROTTLES HAVE A BANK OF 6 SWITCHES CONNECTED TO EACH THROTTLE LEVER.  CUSTOMER`S SQUAWK WAS THAT THE DETENT INDICATOR LIGHTS (MOUNTED ON THE INSTRUEMENT PANEL) FOR THE INDIVIDUAL THROTTLE WERE INOPERATIVE.  TROUBLESHOT SYS AND FOUND 2 OUT OF THE 6 SWITCHES DEFECTIVE ON THE LT SIDE AND 3 OUT OF THE 6 SWITCHES DEFECTIVE ON THE RT SIDE.  THESE SWITCHES ARE FOR THE  "HEADS UP" INDICATOR ONLY.  THE BANK OF 6 SWITCHES WERE REPLACED ON THE LT AND RT SIDE AND ADJUSTED IAW THE MM AND ALL WORKED OK
