## Discrepancy

FOURTH INCIDENT INVOLVING THIS SAME STARTER SOLENOID INTAILING SHORTING OUT INTERNAL WINDING CAUSING STARTER TO MALFUNCTION.  THE FORMER THREE OCCASIONS, THE STARTER FAILED TO ROTATE (SOLENOID STUCK IN THE OPEN POSITION)  ON THIS OCCASION, STARTER TURNED AS SOON AS THE MASTER WAS TURNED ON ( SOLENOID STUCK IN CLOSED POSITION).  ON THIS OCCASION, THE BATTERY WAS NOT FULLY CHARGED AND CAUSED A HIGH CURRENT DRAW TO THE STARTER.  A DICECTEDED SOLENOID REVELED SHORTED WINDINGS.  THIS SWITCH WAS IN OPERATION NOT MORE THAN 6 MONTHS.
