Magneto Coils - Arctic Cat ATV 250 Utility 2009 Service Manual

RESISTANCE (LO Beam)
1. Connect the red tester lead to the white wire; then
connect the black tester lead to the brown/black
wire.
2. With the dimmer switch in the LO position, the
meter must show less than 1 ohm.
NOTE: If the meter reads more than 1 ohm of
resistance, troubleshoot
switch/component or the connector.
RESISTANCE (Starter Button)
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 yellow/red
wire.
3. With the starter button depressed, the meter must
show less than 1 ohm.
4. With the starter button released, the meter must
show an open circuit.
NOTE: If the meter does not show as specified,
replace the switch/component or connector.
RESISTANCE (Emergency Stop)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the brown/blue wire;
then connect the black tester lead to the
black/white wire.
3. With the switch in the OFF position, the meter
must show an open circuit.
4. With the switch in the RUN position, the meter
must show less than 1 ohm.
NOTE: If the meter shows more than 1 ohm of
resistance, troubleshoot
switch/component or the connector.
RESISTANCE (Reverse Override)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the green/red wire;
then connect the black tester lead to the blue/red
wire. The meter must show an open circuit.

VOLTAGE (Charging Coil - Output)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the positive battery
post; then connect the black tester lead to the nega-
tive battery post.
3. With the engine running at a constant 5000 RPM
(with the headlights on), the meter must show
14-15.5 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 black and white one on the right
side of the engine just above the brake cable adjuster.
NOTE: Test the connector that comes from the
engine.
1. Set the meter selector to the AC Voltage position.
2. Test between the three yellow wires for a total of
three tests.
3. With the engine running at the specified RPM, all
wire tests must show as specified.
! CAUTION
Do not run the engine at high RPM for more than 10
seconds.
NOTE: If both voltage tests failed, check all con-
nections, etc., and test again. If no voltage is
present, replace the stator assembly.
RESISTANCE (Charging Coil)
! CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
1. Set the meter selector to OHMS position.
2. Test between the three yellow wires for a total of
three tests.
3. The meter reading must be within specification.
