## Discrepancy

DURING ANNUAL INSPECTION, OWNER COMMENTED ABOUT DIM OR FLICKERING LIGHTS AND INTERMITTENT INSTRUMENT FAILURE.  DURING TROUBLESHOOTING PROCESS, A VOLTAGE DROP WAS FOUND ACROSS CONNECTION OF BATTERY CONTACTOR (24V IN AND 10 TO 12 OUT).  CONTACTOR REMOVED AND CUT OPEN - REVEALED BURNED/WORN CONTACTS INSIDE CONTACTOR BODY.  SUGGEST CHECK FOR VOLTAGE DROP ACROSS ALL CONTACTORS WITH THIS PART NUMBER.
