Ignition Coil – Bench Test
1. Remove the coil from the engine. See Ignition Coil Removal, Section 13, Page 13-29.
2. Using a multimeter set to 200 ohms, measure the primary coil resistance.
2.1. Place the black (–) probe of the meter on the terminal on the ignition coil (1), and place the red (+) probe on
the core (2) (Figure 11-29, Page 11-27) .
2.2. If the resistance is not between 0.6 - 1.7 ohms, replace the ignition coil.
3. Using a multimeter set to 20k ohms, measure the resistance of the secondary coil and spark plug cap together.
3.1. Place the red (+) probe of the meter into the end of the spark plug cap that normally connects to the spark
plug (3) and place the black (–) probe on the core (2) (Figure 11-30, Page 11-27) .
3.2. If the resistance is between 12.0k - 14.0k ohms, the secondary coil and spark plug cap are within
acceptable limits; proceed to step 6. If the resistance is not between 12.0k - 14.0k ohms, the spark plug cap
and secondary coil must be tested independently from each other.
4. If not previously tested, test the spark plug cap separately from the secondary coil.
4.1. Remove the rubber gasket (1) on the plug cap (2) by rolling back the gasket onto the spark plug wire (3)
(Figure 11-25, Page 11-25) .
4.2. Remove the cap from the wire by turning the cap counterclockwise three or four revolutions while gently
pulling it off the wire (Figure 11-26, Page 11-25) .
4.3. Using a multimeter set to 20k ohms, place the red (+) probe of the multimeter into the end of the spark plug
cap that normally connects to the spark plug and place the black (–) probe into the end of the cap with the
internal screw
(Figure 11-27, Page 11-26) . If the resistance is not between 4.5k - 6.0k ohms, the cap has
failed and must be replaced. Proceed to the next step with the spark plug cap still removed.
5. Test the secondary coil separately from the spark plug cap.
5.1. Using a multimeter set to 20k ohms, place the red (+) probe of the meter into the end of the spark plug wire
and place the black (–) probe on the core (2) (Figure 11-31, Page 11-28) . If the resistance is between 6.0k
- 11.0k ohms, the secondary coil is within acceptable limits. If the resistance is not between 6.0k - 11.0k
ohms, the ignition coil has failed and must be replaced.
6. If the preceding procedures indicate that the ignition coil resistance readings are within acceptable ranges, but
the coil fails to function properly, replace the ignition coil and cap.
