## Discrepancy

THE WIRING, CONNECTOR AND PINS IN THE PANEL ASSY OVERHEAD SWITCHES ARE MELTED AND SHORTED OUT.  THE CONNECTOR IS P5 AND THE WIRES ARE L1B20, L1D20, AND L3B18 WHICH GOES TO THE LANDING LIGHT SWITCH, NAV. LIGHTS SWITCH, AND THE STROBE SWITCH.  BELIEVED THE CAUSE IS HIGHTER RESISTANCE WAS CREATED AND WITH THE AMOUNT OF CONTINUOUS CURRENT FLOW CREATED ENOUGH HEAT TO MELT THE CONNECTORS AND BURNED THE PINS.  ECOMMENDATION IS TO US A HIGHTER AMP CONNECTOR AND PINS.
