## Discrepancy

PILOT REPORTED SPARKS COMING FROM UNDER THE INSTRUMENT PANEL UPON ENERGIZING THE IGNITION SWITCH.  UPON FURTHER INVESTIGATION, FOUND THE WIRE BUNDLE FOR THE CIRCUIT BREAKERS ADJACENT TO THE IGNITION SWITCH WAS TOO LONG AND A WIRE IN THE BUNDLE HAD CHAFED ON AN IGNTION SWITCH POLE EVENTUALLY ARCING.
