Ignition Coil: Testing and Inspection

Step 10:

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

Terminal Resistance [at 25°C (77°F)]
7 - 8 (Primary coil) 0.5 - 1.0 ohms
7 - 9 (Secondary coil) Approximately 12 K Ohms

For checking secondary coil, remove distributor cap and measure resistance between coil tower metal tip 9 and terminal. If NG, replace distributor assembly as a unit.
