## Discrepancy

VENDOR UNKNOWN.  IN JULY, APPROXIMATELY 40 CYCLES, THE SOLENOID WOULD NOT FUNCTION.  REMOVED/REPLACED WITH GOOD UNIT.  DRILLED 4 RIVETS ON CAP AND FOUND THE ENTIRE INTERNAL PLUNGER/CONTACT DISC/STUDS COVERED WITH CORROSION.  SUBMITTER STATED WHATEVER IS USED PRIOR TO ASSEMBLY IS CAUSING SAME.
