## Discrepancy

CUSTOMER SAID MAG INOPERATIVE.  BENCH TEST CONFIRMED.  INSPECTION SHOWED CRACKED COIL.  COIL RESISTANCES MEET SPECS, BUT MAG DOES NOT SPARK CONSISTENTLY.  INSTALLED NEW COIL (PN M3975) AND RE-TESTED.  MAG TESTS GOOD.  CONDENSER TESTED GOOD.  SUSPECT SECONDARY CIRCUIT OUTPUT ARCING TO GROUND INTERNALLY.
