Component Testing Procedures

IGNITION COIL
1. Disconnect ignition coil harness connector.
2. Check resistance as shown in the figure.




If NG, replace ignition coil.




3. For checking secondary coil, remove distributor cap.
4. Check resistance between ignition coil harness connector terminal 7 and the secondary terminal on the distributor head.
If NG, replace distributor.




POWER TRANSISTOR
1. Disconnect power transistor harness connector.
2. Check power transistor resistance between terminals 2 and 8.




If NG, replace distributor.




RESISTOR
1. Disconnect resistor harness connector.
2. Check resistance between terminals 1 and 2.

Resistance:
Approximately 2.2 k.ohms [at 25°C (77°F)]

If NG, replace resistor.
