NOTES
Keep the following notes in mind when diagnosing an
electrical problem.
G Refer to wiring diagram for stator and
electrical component resistance
specifications.
G When 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
theleadresistance.
G Become 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.
G Voltage, 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.
G Pay attention to the prefix on the
multimeter reading (K, M, etc.) and the
position of the decimal point.
G For 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.
The ignition timing marks are stamped on the outer
diameter of the flywheel. Ignition timing must be
inspected with the engine at room temperature (68qF
/20q C) to obtain the most accurate reading.
2. With the transmission in neutral, start the engine
and set engine speed to 3500 r 50 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 may
retard approximately 2q when the engine is warm.
If the ignition timing is not within the specified range,
test components for proper function.
