NOTES
Keep the following notes in mindwhen diagnosingan
electrical problem.
GRefer to wiring diagram for stator and
electrical component resistance
specifications.
GWhenmeasuringresistanceof acomponent
that has a resistance value under10
Ohms, remember to subtract meter lead
resistancefromthereading. Connectthe
leadstogetherandrecordtheresistance.

GBecome familiar with the operation of your
meter. Be sure leads are in the proper
jackforthetestbeingperformed(i.e.10A
jack for current readings). Refer to the
Owner’s manual included with your
meter for more information.
GVoltage,amper age,andresis t ancevalues
included in this manual are obtained
with a Fluket 77 Digit al Mult im et er
(P V--43568). This meter is used for
when diagnosing elect r ical problems .
Readings obt ained wit h other m et ers
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/magnetohousing. Removethecheckplug.
NOTE: The ignitiontimingmarks arestampedonthe
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
holeandcheck theignitiontiming. NOTE: Donot
allowtheenginetowarmup. Thetimingwillretard
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
