Ignition Coil: Testing and Inspection

Component Overview:

1. With ignition switch in the off position, disconnect the primary wires from the ignition coil.

2. Using an appropriate ohm meter connect the test leads to the primary coil terminals.

Primary Coil Resistance: 0.72 - 0.88 ohm

3. Connect the ohm meter leads between the positive primary terminal and the secondary high voltage terminal.

Secondary Coil Resistance: 10.3k - 13.9k ohms

4. Inspect the primary and secondary coil connections.

5. Inspect the ignition coil for signs of physical damage such as:
- Cracks in the case
- Signs of leakage
- Carbon tracks
- Burned, melted or discolored plastic

6. If any of the above test results are not within specifications or physical damage is apparent, replace the ignition coil.
