## Discrepancy

AFTER ENGINE START THE MAP, ENGINE PERCENT POWER AND FUEL FLOW INDICATIONS BECAME INOPERATIVE. ACFT WAS NOT FLOWN. FLIGHT CREW SQUAWKED PROBLEM AND BROUGHT ACFT AND TIN TO MX.  GROUND RUN-UP PERFORMED AND AMT WAS ABLE TO DUPLICATE PROBLEM.  ACFT ENGINE COWLING WAS REMOVED TO DISCOVER THE MAP/FUEL FLOW INDICATION WIRE/ LOOM ASSY CHARRED AND BURNED. THE HOT SPOT WAS ATTRIBUTED TO A DEFECTIVE STARTER (MODEL C24ST3) THAT SHOWED EVIDENCE OF AN INTERNAL ELECTRICAL ARCH THAT HAD BURNED A HOLE ENTIRELY THROUGH THE STARTER HOUSING. THE EXCESSIVE AMOUNT OF HEAT, SPARK AND POSSIBLE FIRE DUE TO THE DEFECTIVE STARTER HAD MELTED THE WIRE LOOM AND COMPROMISED THE FUNCTIONALITY OF THE INDICATOR WIRE BUNDLE. STARTER REMOVED FROM ACFT.
