ELECTRICAL SYSTEM L4100, WSM
9-S17
(EU)
(9) Combination Switch
1. Turn off the main switch (1).
2. Remove the panel board (2).
3. Perform the following checkings.

Connector Voltage (Wire Harness Side)
1. Disconnect the 8P connector (1) from the combination switch.
2. Measure the voltage with a voltmeter across the connector B1
terminal and chassis when the main switch is OFF position.
3. If the voltage differs from the battery voltage, the wiring harness
is faulty.
4. Measure the voltage with a voltmeter across the connector B2
terminal and chassis when the main switch is ON position.
5. If the voltage differs from the battery voltage, check the wiring
harness and main switch.

Head Light Switch Continuity when Setting Switch at OFF
Position
1. Disconnect the 8P connector from the combination switch.
2. Set the light switch to the OFF position.
3. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal, the B1 terminal to the 1 terminal and
the B1 terminal to the 2 terminal.
4. If infinity is not indicated, renew the switch.
