NOTES
Keep the following notes in mind when diagnosing an
electrical problem.
GAll Voltage, amperage, and resistance
values in this manual were obtained
with a Fluket 77 Digital Multimeter.
This meter is used for diagnosing
electrical problems. Readings obtained
with other meters may differ.
GRefer to wiring diagram for stator and
electrical component resistance
specifications.
GWhen measuring resistance of a
component that has a resistance value
under 10 Ohms, remember to subtract
meter lead resistance from the reading.
Connect the leads together and record
the resistance. The resistance of the
component is equal to tested value minus
the lead resistance.
GBecome familiar with the operation of your
meter. Be sure leads are in the proper
jack for the test being performed (i.e. 10A
jack for current readings). Refer to the
Owner’s manual included with your
meter for more information.
GPay attention to the prefix on the
multimeter reading (K, M, etc.) and the
position of the decimal point.
GFor resistance readings, isolate the
component to be tested. Disconnect it
from the wiring harness or power supply.
TIMING CHECK PROCEDURE
1. The ignition timing check hole is in the starter
recoil/magneto housing. Remove the check plug.
Check Plug
NOTE: The ignition timing marks are stamped on the
outside of the flywheel. Ignition timing must be
inspected with the engine at room temperature (68°F
/20° C).
2. With the transmission in neutral, start the engine
and open throttle until engine is at 5000 ± 200
RPM.
3. Direct the timing light at the ignition timing check
hole and check the ignition timing. NOTE: Do not
allow the engine to warm up. The timing will retard
approximately 2° when the engine is warm.
If the ignition timing is not within the specified range,
test the ignition components for signs of failure.
The timing tag on the flywheel indicates the direction
of rotation and the scale for ignition timing.
