Magneto Coils (650 V-Twin) - Arctic Cat 400 Service Manual

NOTE: The battery must be at full charge for
these tests.
Magneto Coil (Trigger)
1. Set the meter selector to the DC Voltage posi-
tion.
2. Connect the red tester lead to the green wire;
then connect the black tester lead to the blue
wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.

1. Set the meter selector to the DC Voltage posi-
tion.
2. Connect the red tester lead to the yellow wire;
then connect the black tester lead to the white
wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.
PEAK VOLTAGE (500/650 H1)
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.

VOLTAGE
(Regulator/Rectifier - Output)
1. Set the meter selector to the DC Voltage posi-
tion.
2. Connect the red tester lead to the positive bat-
tery 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 DC volts.
! CAUTION
Do not run the engine at high RPM for more than 10
seconds.
NOTE: If voltage is lower than specified, test sta-
tor coil - no load.
VOLTAGE
(Stator 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 posi-
tion.
2. Test between the three black wires for a total of
three tests.
