IGNITION SYSTEM

8. Set the multimeter to the ohms (Ω) scale.

• If the multimeter shows continuity, replace the

module.

• If the multimeter does not show continuity,

check the wire for a break and check the ground

connection. See Figure 7.9.

The module

The coil in this ignition system is an inductive discharge

magneto, contained in a single module.

• The inductive discharge magneto has a two leg

design.

• The magneto is energized by the passing of a

pair of magnets mounted in the flywheel.

• Ignition timing is set by the location of the fly-

wheel in relation to the crankshaft. Proper timing

is maintained by a steel key.

Normal performance of the coil is to produce at least

10,000 volts at starter-rope pull-through speed.

The presence or absence of strong spark, with the stop

switch known to be good, is generally enough to iden-

tify the ignition coil as good or bad. Resistance read-

ings may help confirm the source of the failure, but are

generally meaningless because they only measure a

small part of the module.

NOTE: Presence of a weak spark maybe the

result of an improper air gap. The air gap space

should be .008”-.016” (.2-.4mm).

Simple spark-testers are readily available and inexpen-

sive. Thexton Part # 404 is available from a variety of

retailers, and similar units are available form other

manufacturers. See Figure 7.10.

NOTE: If the complaint is that the engine quits

running when it gets warm, the ignition module

should be tested with the engine at normal oper

ating temperature.
