Ignition Control Module: Testing and Inspection
INSPECTION OF IGNITER1. TURN IGNITION SWITCH ON
2. CHECK POWER SOURCE LINE VOLTAGE
(a) Disconnect the wiring connector for brown wire and yellow wire.
(b) Using a voltmeter, connect the positive (+) probe to the brown wire for the wire harness side and the negative (-) probe to body ground.
Voltage: Approx. 12 V
3. CHECK POWER TRANSISTOR IN IGNITER
(a) Connect the wiring connector for brown wire and yellow wire.
(b) Using a voltmeter, connect the positive (+) probe the yellow wire for the igniter side and the negative (-) probe to body ground.
Voltage: Approx. 12 V
(c) Unplug the wiring connector from the distributor.
(d) Using a dry cell battery (1.5 V), connect the positive (+) pole of the battery to the pink wire terminal and the negative (-) pole to the white wire terminal.
CAUTION: Do not apply voltage more than 5 seconds to avoid destroying the power transistor in the igniter.
(e) Using a voltmeter, connect the positive (+) probe to the yellow connector for the igniter side and the negative (-) probe to body ground.
Voltage: 8 - 10 V
If a problem is found, replace the igniter.
