Troubleshooting the Ignition System
The purpose of the ignition system is to provide and
deliver a spark to ignite the fuel/air charge in the cylin-
der at the proper time.
The ignition system consists of:
• The flywheel
• The module
• The spark plug
• The engine run switch and wires
NOTE: To service the spark plug see the Chap-
ter 2: Maintenance.
1. To test the ignition system:
1a. Make sure the engine run switch is in the on
(1) position.
1b. Disconnect the spark plug wire.
1c. Connect a spark tester to the spark plug
wire.
1d. Connect the other end of the spark tester to
the engine block. See Figure 4.1.
CAUTION: Never remove the spark plug and
hold it against the engine block to test for spark.
The fuel/air mix coming out of the spark plug
hole will catch on fire.
NOTE: The spark should be a minimum of 10 Kv
(10,000 volts) at pull over speed.

1e. Rapidly rotate the engine while watching the
spark tester for sparks.
NOTE: The starter is part of the engine cover
and therefore can not be used to rotate the
engine. A cordless drill can be used to rotate the
engine. See Figure 4.2.
IMPORTANT: Never use an impact wrench to
rotate the engine. It wil result in a boken crank-
shaft.
1f. If no sparks are seen in the spark tester fur-
ther testing is required.
