Ignition Module Resistance Table
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.
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.
