## Discrepancy

ESCAPE SLIDE PRESSURE WARNING LIGHT CAME ON AT 4R.  *S/D*  THE ESCAPE SLIDE PRESSURE WARNING LIGHT WAS FALSELY ILLUMINATED DUE TO CORROSION ON REMOTE PRESSURE INDICATOR BATTERY PACK.  A VISUAL INSPECTION OF THE BATTERY PACK CONFIRMED THE PRESENCE OF CORROSION ON CONTACTS AND PARTIAL SEPARATION OF THE BLACK WIRE DUE TO CORROSION.  TESTING OF THE BOTTLE PER MM 25-61-03 WAS PERFORMED, AS WELL AS A COLD SOAK OF THE BOTTLE AND SLIDE AT 16 DEGREES AMBIENT TEMPERATURE, CONFIRMING A FULLY CHARGED BOTTLE.REPLACEMENT OF THE BATTERY PACK HARNESS WAS ACCOMPLISHED WHICH RETURNED DOOR 4R SLIDE INDICATION TO SERVICEABLE STATUS.
