Testing Handlebar
Warmer/Thumb
Warmer Switch
(EFI Models/Panther 570)
REMOVING/TESTING
1. Remove the handlebar pad.
2. Remove the four screws securing the left-side han-
dlebar control assembly; then remove the control
assembly from the handlebar.
3. Disconnect the handlebar/thumb warmer harness
from the switch.
4. With the thumb warmer toggle in the low position,
connect one ohmmeter lead to pin (C) and the
other ohmmeter lead to pin (B). The meter must
read 1 ohm or less resistance.

5. With the thumb warmer toggle in the high posi-
tion, connect one ohmmeter lead to pin (C) and the
other ohmmeter lead to pin (A). The meter must
read 1 ohm or less resistance.
NOTE: If either test does not read within specifi-
cation, replace the complete control assembly.
6. With the handwarmer toggle in the low position,
connect one ohmmeter lead to pin (C) and the
other ohmmeter lead to pin (D). The meter must
read 1 ohm or less resistance.
7. With the handwarmer toggle in the high position,
connect one ohmmeter lead to pin (C) and the
other ohmmeter lead to pin (E). The meter must
read 1 ohm or less resistance.
NOTE: If either test does not read within specifi-
cation, replace the complete control assembly.
INSTALLING
1. Connect the handlebar/thumb warmer harness to
the switch; then place the control assembly on the
handlebar.
2. Secure with the four screws; then install the han-
dlebar pad.
Testing Thumb
Warmer Switch
(Bearcat 570/Panther 370/
Z 370/Z 570)
1. Remove the handlebar pad.
2. Disconnect the thumb warmer two-wire connector.
3. In the switch connector, connect one ohmmeter
lead to each terminal.
4. With the switch in the OFF position, the meter
must read an open circuit. With the switch in the
ON position, the meter must read 1 ohm or less
resistance.
5. Connect the leads; then install and secure the han-
dlebar pad.
Testing Passenger
Handwarmer Switch
1. Disconnect the lead wires from the switch.
2. With the switch in the LO position, connect one
ohmmeter lead to the green/white wire at the con-
nector; then connect the other ohmmeter lead to
the brown wire at the connector. The meter must
read less than 1 ohm of resistance.
3. With the switch in the MED position, connect one
ohmmeter lead to the green/red wire at the connec-
tor; then connect the other ohmmeter lead to the
brown wire at the connector. The meter must read
less than 1 ohm of resistance.
4. With the switch in the HI position, connect one
ohmmeter lead to the green/blue wire at the con-
nector; then connect the other ohmmeter lead to
the brown wire at the connector. The meter must
read less than 1 ohm of resistance.
Testing Passenger
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.
