## Discrepancy

FOUND MAGNETO FILTER DEFECTIVE WHEN SUBJECT TO MAGNETO P-LEAD VOLTAGE OR HIGH TENSION LEAD TESTER VOLTAGE.  REGULAR OHM CHECK DID NOT PICK UP DEFECT.  ENGINE WOULD RUN INTERMITTENTLY BAD ON THIS MAGNETO.  THIS IS AN AFTER-MARKET PART INSTALLED IN LINE WITH P-LEADS TO REDUCE MAGNETO P-LEAD VOLTAGE INTERFERENCE.
