Electrical System and Components
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 snug
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.)
. On a twin cylinder engine,
repeat these 6 steps to set the opposite side
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 on a twin), your problem should be
corrected. Go to step 4 of Test 5.
b. If there is still a spark problem, perform all
of Test 5.
Test 5. Test the SAM.
1. Trace the red power source lead from the SAM to
the harness connection. Separate the connector
and connect the red lead of a DC voltmeter to the
harness terminal. Trace the ground lead from the
SAM (black on singles, green on twins) to the
grounding screw. Connect the black voltmeter lead
to the eyelet terminal of the ground lead or the
ground screw/bolt. Check the voltage with the key
switch in both the “START” and “RUN” positions.
A minimum of 7.25 volts must be present.
