SOLID STATE IGNITION SYSTEM (NON-
ALTERNATOR TYPE).
CAUTION: Do not attempt to crank engine with
the primary wire of the transformer disconnected.
Also do not allow the primary wire of the
transformer to be grounded or arc. A broken
wire causing an open circuit to or in the transformer
can also cause permanent damage. See Step
2.
1. Preliminary Tests
Spark Test . . .Check for spark.
Perform the following visual tests:
HIGH TENSION LEAD . . .Inspect for cracks or
indications of arcing. Replace the transformer
if a questionable lead is found.
LOW TENSION LEADS . . .Check all leads for
shorts. Check ignition cut-off lead to see that
unit is not grounded out. Repair leads if possible,
or replace.
FLYWHEEL . . .Check magnets for strength. Check
key and keyway. Be sure that the key locks the
flywheel to the crankshaft.
2. After the above visual checks are made the
transformer and solid state components can be
checked using a Merc-O-Tronic, Graham-Lee or
similar tester.
NOTE: Before using parts for tests, be sure any
problem which caused replacement is corrected
first.
3. When testers are not available... Use new
replacement parts as test for possible failed parts.
SOLID STATE STATOR - Replace and test for
spark. Time the magneto by turning
counterclockwise as far as it will go. Tighten retaining
screws to 5-7 foot pounds (6.8 - 12.4 mm).
STATOR PLATE ASSEMBLY (20 AMP SYSTEM).
Previous tests also apply, except for the following:
1. Test the ignition unit first. If good, remove flywheel
and check coil for continuity.
2. Determine if correct flywheel is used, if previously
replaced. The flywheel used for a 20 amp system
is not compatible with flywheel used on a 10
amp systems.
3. The stator cannot be turned once secured with
stator bolts.
