## Discrepancy

FOUND EMERGENCY LIGHTS ON BUT SWITCHES WERE OFF.   PULLED CIRCUIT BREAKERS, LIGHT WENT OUT.  SEVERAL HOURS LATER,  ON PREFLIGHT, DISCOVERED BLACK SOOT COMING OUT OF ENGINE COWLING.   DISCOVER WHAT APPEARS TO BE AN ELECTRICAL FIRE HAD OCCURRED.   APPEARS THAT A RESISTOR SHORTED OUT AGAINST THE BATTERY RELAY, AND MELTED PLASTIC COVER AND CREATED A BURNED ASH OVER THE RELAY BOX AND SURROUNDING AREAS.  NO STRUCTURAL DAMAGE TO ENGINE MOUNT OR FIREWALL/PRESSURE BULKHEAD HAS BEEN NOTED.
