Ignition Primary Circuit Check

  1. Attach a voltmeter negative lead to side of distributor. On Pulsar and Sentra models connect voltmeter positive lead to Blue wire removed from IC ignition unit.
  2. On Stanza, and 200SX models, connect the voltmeter positive lead to "I" terminal of IC ignition unit connector, and then to the "E" terminal of IC ignition unit connector. See Fig 1.
  3. Turn ignition switch to "ON" position after lead has been attached to each terminal. Voltage readings should be 11.5-12.5 volts. If reading is below specifications, check Coil Primary Resistance if not previously done. If voltage is correct, proceed to IC IGNITION UNIT GROUND CIRCUIT CHECK .

  4. If voltage is 11.5-12.5 volts, check ground circuit. See IC IGNITION UNIT GROUND CIRCUIT CHECK . If voltage reading is below 11.5 volts, check Coil Primary Resistance, if not previously done.
