3. Turn the ignition switch to the ON position and
select 2 WD on the front drive selector switch;
then while watching the meter (12 D.C.volts),
select the lock position on the differential lock.
The meter should drop to 0 volts.

NOTE: It may be necessary to rock the ATV
slightly to engage the differential lock fully.
Magneto Coils
VOLTAGE (Charging Coil - Output)
1. Set the meter selector to the D.C. Voltage position.
2. Connect the red tester lead to the positive battery
post; then connect the black tester lead to the
negative battery post.
3. With the engine running at a constant 5000 RPM
(with the headlights on), the meter must show
14-15 D.C. volts.

NOTE: If voltage is lower than specified, test
charging coil - no load.
VOLTAGE
(Charging Coil - No Load)
The connector is the white one on the right side behind
the engine.

NOTE: Test the connector that comes from the
engine.
1. Set the meter selector to the A.C. Voltage position.
2. Test between the three black wires for a total of
three tests.
KX387
3. With the engine running at a constant 3000 RPM,
all wire tests must show 39-59 A.C. volts.

NOTE: If both charging coil tests failed, check all
connections, etc., and test again. If no voltage is
present, replace the stator assembly.
RESISTANCE (Charging Coil)
1. Set the meter selector to OHMS position.
2. Test between the three black wires for a total of
three tests.
KX387
3. The meter reading must be within specification.
RESISTANCE (Trigger Coil)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the black/white wire;
then connect the black tester lead to the blue wire.
The meter reading must be within specification.
PEAK VOLTAGE

NOTE: All of the peak voltage tests should be
made using the Fluke Model 73 Multimeter (p/n
0644-191) with Peak Voltage Reading Adapter (p/n
0644-307). If any other type of tester is used, read-
ings may vary due to internal circuitry.

NOTE: The battery must be at full charge for
these tests.
! CAUTION
Do not run the engine at high RPM for more than
10 seconds.
! CAUTION
Do not run the engine at high RPM for more than
10 seconds.
! CAUTION
Always disconnect the battery when performing
resistance tests to avoid damaging the
multimeter.
