Handwarmer Elements

„NOTE: During this test, resistance will vary due
to temperature; therefore, this test should be made
at room temperature of 20° C (68° F).

1. Disconnect the lead wires from the main wiring

harness.

2. For the LO position, connect one ohmmeter lead

to the green/white wire from the element; then

connect the other ohmmeter lead to the green wire

from the element. The meter must read between

23.8-32.2 ohms.

3. For the MED position, connect one ohmmeter lead

to the green/red wire from the element; then con-

nect the other ohmmeter lead to the green wire

from the element. The meter must read between

13.6-18.4 ohms.

4. For the HI position, connect one ohmmeter lead to

the green/blue wire from the element; then connect

the other ohmmeter lead to the green wire from the

element. The meter must read between 8.7-11.7

ohms.

Testing 

Speedometer Sensor

(EFI Models/F 570/T570)

„NOTE: The following test should be made using
MaxiClips and the Fluke Model 73 Multimeter set to
the DC Volt scale.

„NOTE: Prior to testing the sensor, inspect the
three-wire connector on the sensor harness for
contamination, broken pins, and/or corrosion.
With the engine running, note that there is a power
supply of 10.8-13.2 DC volts at the main harness/
speedometer connector.

ZJ210B

1. Elevate the rear of the snowmobile onto a suitable

safety stand.

2. Set the meter selector to the DC Voltage position.

3. At the sensor side of the plug-in, connect the red

maxiclip and meter lead to the white (center) lead;

then connect the black maxiclip and meter lead to

the black lead.

4. Connect a positive 12-volt DC power supply to the

red/blue wire; then connect a negative cable to the

black wire from the main harness side of the plug-

in.

5. Rotate the driven pulley. The meter must read 0

volts and 12 volts alternately.

„NOTE: No voltage should appear when the tab
(A) of the brake disc jam nut is aligned with the
sensor (B).

Testing Reverse 

Alarm Switch 

BEARCAT 570/PANTHER 370/

F 570/T570

„NOTE: On the Bearcat 570/Panther 370, the
switch is in a bracket on the chain case. On the F
570/T570, the switch is on the shift pivot lever
bracket.

1. Disconnect the alarm switch two-wire connector.

2. Connect one ohmmeter lead to the yellow wire;

then connect the other ohmmeter lead to the

orange wire.

3. With the lever in the reverse position, the meter

must read less than 1 ohm of resistance. With the

lever in the forward position, the meter must read

OL (open).

„NOTE: If the meter does not read as specified in
either test, the switch is defective and must be
replaced.

CROSSFIRE/F-SERIES/M-SERIES

„NOTE: The switch is located on the gear case
above the left-side footrest.

1. Disconnect the alarm switch two-wire connector.

2. Remove the six torx-head cap screws securing the

left-side footrest to the chassis and remove the

footrest; then un-thread the alarm switch from the

gear case.

3. Connect one ohmmeter lead to the black wire; then

connect the other ohmmeter lead to the violet/

black wire.

4. With the reverse button pressed in, the meter must

read less than 1 ohm of resistance. With the

reverse button released, the meter must read OL

(open).

„NOTE: If the meter does not read as specified in
either test, the switch is defective and must be
replaced.

Testing Shift 

Actuator Switch

(Electronic Reverse Models)

„NOTE: The shift actuator switch is located on the
right-side handlebar control.

1. Disconnect the actuator two-wire connector from

the handlebar control.

2. Connect one ohmmeter lead to the black wire; then

connect the other ohmmeter lead to the white/vio-

let wire.

3. With the reverse button pressed in, the meter must

read less than 1 ohm of resistance. With the reverse

button released, the meter must read OL (open).

„NOTE: If the meter does not read as specified in
either test, the switch is defective and must be
replaced.

Testing Shift Actuator 

(Electronic Reverse Models)

„NOTE: The actuator is located on the gear case
above the left-side footrest.

1. Disconnect the actuator two-wire connector.

2. Connect one meter lead to the red/orange lead of

the two-wire actuator connector; then connect the

other meter lead to the other lead in the connector.

3. Secure the belt guard into position; then start the

engine.

4. Press and release the reverse button; there should

be a flash of DC battery voltage indicated on the

meter. Again press and release the reverse button;

there should be a flash of DC battery voltage indi-

cated on the meter.

„NOTE: If the meter indicates a flash of voltage
but the actuator does not function, the actuator is
defective and must be replaced.

„NOTE: If the meter does not indicate a flash of
voltage, troubleshoot the main harness.

! CAUTION

Do not run the engine without the belt guard secured
in place.
