EMR System Check

  1. Start engine and run at idle speed until it reaches normal operating temperature. Check ignition timing. Then disconnect EMR lead (terminal "R") of 5-terminal module.
  2. If there was no timing change, ground distributor side of EMR lead. If timing retards, there is no trouble in EMR circuit.
  3. If there is no timing change, however, check for an open or grounded EMR lead to distributor. If lead is OK, replace HEI-EMR module in distributor. If lead is not OK, repair or replace it as necessary.
