Ignition Coil: Testing and Inspection

High Tension Cords
1. Remove high-tension cord at ignition coil while gripping its cap.
2. Remove distributor cap installed with high-tension cords.
3. Remove high-tension cord clamp from cylinder head cover.
4. Pull out high-tension cords from spark plugs while gripping each cap.

CAUTION:
- Removal of high-tension cords together with clamps will be recommended so as not to damage their inside wire (resistive conductor).
- For the same reason, pull out each connection by gripping cap portion.

5. Measure resistance of high-tension cord by using ohmmeter.
High-tension cord resistance: 10 - 22 k.ohms/m (3.0 - 6.7 k.ohms/ft)
6. If resistance exceeds specification, inspect distributor terminal and replace high-tension cord(s) and/or distributor cap as required.

CAUTION:
- Never attempt to use metal conductor high-tension cords as replacing parts.
- Insert each cap portion fully when installing high-tension cords.





Ignition Coil
1. Pull out high-tension cord by gripping its cap.
2. Disconnect ignition coil coupler.
3. Measure primary and secondary coil resistances.
Ignition coil resistance (at 20°C, 68°F)
Primary :1.08 - 1.32ohms
Secondary: 22.1 - 29.9 kohms
4. If resistance is out of specification, replace coil with new one.
