Pick-Up Coil Resistance Check

  1. Turn ignition switch off. Disconnect 2-wire distributor connector. Connect an ohmmeter set to x100 scale with one lead touching each terminal of distributor harness connector.
  2. Pick-up coil resistance should be 700-800 ohms. If not, replace pick-up coil assembly. If system works intermittently, be sure pick-up coil wire in distributor is properly grounded. See Figure.
