L3560, L4060, L4760, L5060, L5460, L6060, WSM

(2) Main Switch (CABIN Type)

Main Switch at ON Position
1. Turn the main switch "ON" position.
2. Measure the resistance across the B terminal and the AC
terminal.
3. If 0 ohm is not indicated, renew the main switch.
Resistance B terminal – AC terminal
A: Main Switch Side Connector 4C
Main Switch at START Position
1. Turn and hold the main switch at the "START" position.
2. Measure the resistances across the B terminal and the AC
terminal, and across the B terminal, and the ST terminal.
3. If 0 ohm is not indicated, renew the main switch.
B terminal – AC terminal
Resistance
B terminal – ST terminal
A: Main Switch Side Connector 4C
Connector Voltage
1. Measure the voltage across the connector B terminal and
chassis.
2. If the voltage differs from the battery voltage (11 to 14 V), the
wiring harness is faulty.

A: Wire Harness Side Connector 6G
Main Switch at ACC Position
1. Turn the main switch ACC position.
2. Measure the resistance across the B terminal and the ACC
terminal.
3. If 0 ohm is not indicated, renew the main switch.
Resistance B terminal – ACC terminal
A: Main Switch Side Connector 6G
Main Switch at Key ON Position
1. Turn and hold the main switch at the "ON" position.
2. Measure the resistances across the B terminal and the ACC
terminal, across B terminal and IG1 terminal and B terminal and
IG2 terminal.
3. If 0 ohm is not indicated, renew the main switch.
B terminal – ACC terminal
Resistance B terminal – IG1 terminal
B terminal – IG2 terminal
