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 position,
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 specifica-
tion, 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 specifica-
tion, replace the complete control assembly.
INSTALLING
1. Connect the handlebar/thumb warmer harness to the
switch; then place the control assembly on the han-
dlebar.
2. Secure with the four screws; then install the handle-
bar 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 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.
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 ohm-
meter lead to the green/blue wire at the connector;
then connect the other ohmmeter lead to the brown
wire at the connector. The meter must read less than
1 ohm of resistance.

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 har-
ness.
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 connect
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.

Resistance

NOTE: The element connectors are located at the
rear of the front seat beneath the flap.
1. Disconnect the main harness/element connector.
2. Connect one ohmmeter lead to the red/yellow main
harness connector; then connect the other ohmmeter
lead to the green/red main harness connector. The
meter must read the following ± 5%:
LO 4.32K ohms
MED 3.92K ohms
HI 3.57K ohms
