Ignition Control Module: Testing and Inspection
INSPECTION OF IGNITER1. TURN IGNITION SWITCH ON
2. CHECK POWER SOURCE LINE VOLTAGE
- Using a voltmeter, connect the positive (+) probe to the ignition coil positive (+) terminal and the negative (-) probe to body ground.
Voltage: Approx. 12V
3. CHECK POWER TRANSISTOR IN IGNITER
(a) Using a voltmeter, connect the positive (+) probe to the ignition coil negative (-) terminal and the negative (-) probe to body ground.
Voltage: Approx. 12V
(b) Unplug the wiring connector from the distributor.
(c) Using a dry cell battery (1.5V), 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.
(d) Using a voltmeter, connect the positive (+) probe to the ignition coil negative (-) terminal and the negative (-) probe to the body ground.
(e) Check the voltage reading.
Voltage: 5 - 8V
If a problem is found, replace the igniter
4. TURN IGNITION SWITCH OFF
5. REMOVE TEST EQUIPMENT AND RECONNECT WIRING
