5. Check and/or adjust ignition module air gap(s). An air gap of 0.28/0.33 mm (0.011/0.013 in.) must be maintained
under all three legs of ignition module(s). Checking/adjusting should be performed with parts at room
temperature.
Condition
Possible Cause
Conclusion
Module was not loosened or
replaced.
Ignition Module Air Gap
Check that specified air gap is
present under all three legs. If gap is
correct, reinstall second mounting
screw removed earlier and recheck
gap after tightening.
Module was loosened or replaced.
Ignition Module
Adjust ignition module air gap.
a. Adjust ignition module air gap.
1. Turn flywheel magnet away from module position.
2. Attach module to mounting legs, pull it away from flywheel, and tighten screws to hold it temporarily.
3. Rotate flywheel so magnet is centered under module.
4. Position a 0.30 mm (0.012 in.) feeler gauge between magnet and all three legs of module. Ignition module
air gap is critical to proper system performance. Do not attempt to set it with a business card or folded
microfiche card. Use feeler gauge specified.
5. Loosen mounting screws, allow magnet to pull module down against feeler gauge, and retighten mounting
screws.
6. Rotate flywheel to remove feeler gauge, position magnet back under module, and recheck that specified
gap, minimum of 0.28 mm (0.011 in.), exists under each leg of module. When you are certain gap is
correct, torque module mounting screws to 4.0 N·m (35 in. lb.). Repeat these 6 steps to set other ignition
module.
6. Reattach lead wires to ignition module(s), noting if resistance is felt, indicating a snug fit between male and
female terminals. If any connections do not feel snug, disconnect lead, lightly pinch female terminal with a pliers,
and recheck fit.
7. When integrity of all connections has been verified, retest for spark.
Condition
Possible Cause
Conclusion
Strong, steady spark is now present
on both sides.
