(1) Combination Switch (ROPS Model)

Combination Switch (ROPS Model)
1. Remove the steering wheel and panel lower cover.
2. Disconnect the combination switch connector.
3. Remove the combination switch (1) and perform the following
checks 1) to 8).
(1) Combination Switch
1) Connector Voltage
1. Measure the voltage with a voltmeter across the connector B2,
B4, TL, TR terminal and chassis when the main switch is ON
position.
2. If the voltage differs from the battery voltage, the wiring harness
and main switch is damaged.

2) Head Light Switch Continuity When Setting Switch at OFF
Position
1. Set the light switch to the OFF position.
2. Measure the resistance with an ohmmeter across the B4
terminal to the T terminal, the B4 terminal to the terminal 1.
3. If infinity is not indicated, the head light switch is damaged.

3) Head Light Switch Continuity When Setting Switch at ON
Position
1. Set the light switch to the ON position.
2. Measure the resistance with an ohmmeter across the B4
terminal to the T terminal and the B4 terminal to the terminal 1.
3. If 0 Ω is not indicated, the head light switch is damaged.
