4. With the switch in the HI beam position, connect one
ohmmeter lead to pin (B) and the other ohmmeter
lead to pin (C). 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 HI/LO beam harness to the switch; then
place the control assembly on the handlebar.
2. Secure with the four screws, then install the handle-
bar pad (if applicable).

Warmer Elements
 NOTE: Resistance will vary due to temperature;
therefore, this test should be made at room tempera-
ture of 20° C (68° F).
 NOTE: To access the element connectors, the han-
dlebar control assembly for the side being tested
must be removed.
1. Remove the handlebar pad (if applicable); then dis-
connect the handlebar warmer three-wire connector.
2. In the element connector, connect one ohmmeter
lead to the green/white lead; then connect the other
ohmmeter lead to the green lead.
3. The meter must read between 6.3-7.7 ohms.
4. In the element connector, connect the ohmmeter
between the green/blue and green lead wires on the
2-stroke models or between the green/black and yel-
low lead wires on the 4-stroke models.
5. The meter must read between 12.6 and 15.4 ohms.
6. Replace any element measuring less than or more
than the specified amount.
 NOTE: Repeat test for the other element.
7. Connect the leads; then install the handlebar control
assembly and secure the handlebar pad (if applica-
