## Discrepancy

A MALFUNCTION OCCURRED BETWEEN THE 30 ALPHA PANEL AND STROBE LIGHT SWITCH CAUSING THE STROBE LIGHTS NOT TO WORK.  THE 30 ALPHA PRINTED CIRCUIT BOARD AND STROBE LIGHT SWITCH BOTH SUSTAINED BURN MARKS AND MELTED SOLDER POINTS.  THE CIRCUIT BREAKER FOR THE STROBE LIGHT SYSTEM DID NOT INTERRUPT THE MALFUNCTION.
