ELECTRICAL SERVICE
NOTES
Keep the following notes in mind when diagnosing an
electrical problem.
GRefer to wiring diagram for stator and
electrical component resistance
specifications.
GWhen measuring resistance of a component
that has a resistance value under10
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.
GVoltage, amperage, and resistance values
included in this manual are obtained
with a Fluket 77 Digital Multimeter
(PV--43568). This meter is used for
when diagnosing electrical problems.
Readings obtained with other meters
may differ.
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.
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 set engine speed to 3500 ± 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. Thetiming will retard
approximately 2° when the engine is warm.
If the ignition timing is not within the specified range,
a faulty component is the most likely cause, as
