NOTE: The resistance values apply only to
modules that have been on a running
engine. New service modules may have
higher resistance until they have been
run.
5. Check and/or adjust the 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 the ignition module(s). Checking/
adjusting should be performed with the parts at
room temperature.
a. If the module was not loosened or replaced,
check that the specified air gap is present
under all three legs. If the gap is correct,
reinstall the second mounting screw removed
earlier and recheck gap after tightening.
b. If the gap is incorrect, or the module was
loosened or replaced, adjust the gap as
follows.
1) Turn the flywheel magnet away from the
module position.
2) Attach the module to the mounting legs, pull
it away from the flywheel, and tighten the
screws to hold it temporarily.
3) Rotate the flywheel so the magnet is
centered under the module.
4) Position a 0.30 mm (0.012 in.) feeler gauge
between the magnet and all three legs of
the module. The 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 the feeler gauge
specified.
5) Loosen the mounting screws, allow the
magnet to pull the module down against
the feeler gauge, and retighten the mounting
screws.
6) Rotate the flywheel to remove the feeler
gauge, position the magnet back under
the module, and recheck that the specified
gap, minimum of 0.28 mm (0.011 in.), exists
under each leg of the module.
When you are certain the gap is correct,
torque the module mounting screws to
4.0 N·m (35 in. lb.). Repeat these 6 steps to
set the other ignition module.
6. Reattach the lead wires to the ignition module(s),
noting if resistance is felt, indicating a snug fit
between the male and female terminals. If any
connections do not feel snug, disconnect the lead,
lightly pinch the female terminal with a pliers,
and recheck the fit.
7. When the integrity of all connections has been
verified, repeat the spark test (Test 2).
a. If a strong, steady spark is now present (both
sides). Go to Test 5, step 4.
b. If there is still a spark problem, perform Test 5.
