Ignition Control Module: Testing and Inspection
Ignition Coil And Power Transistor Circuit
To test the Power Transistor / Ignition Coil, located in the distributor, using an analog type circuit tester proceed as follows.
Power Transistor / Ignition Coil Test
POWER TRANSISTOR
1. Disconnect the power transistor / ignition coil connector.
2. Connect a power supply of 1.5v (one dry cell) between power transistor terminals 2 (-) and 4 (+).
3. Check for continuity between terminals 1 (+) and 2 (-).
Continuity
Should exist
4. Remove power from terminals 1 and 2.
5. Check for continuity between terminals 3 (+) and 2 (-).
