IGNITOR Test

  1. Turn ignition on. Connect voltmeter positive probe to ignition coil positive terminal, and negative probe to coil negative terminal. Reading should be approximately 6 volts.
    NOTE: On some Toyota models, step 1)  is replaced by a voltage check between ignition coil negative terminal "e" and resistor terminal "a". This reading should be 12 volts. Either check Is acceptable.
  2. Unplug wiring connector from distributor. Using a 1.5 volt dry cell battery, connect positive battery pole to White wire of 2-pin connector. Connect battery negative pole to Pink wire terminal. See Fig 1.
  3. Again check oil voltage with the 1.5 volt battery installed. Voltage should be approximately zero (0) volts. Turn ignition off, remove test equipment, and reconnect wiring.
