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.

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.

(2) Main Switch (CABIN Type)
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.

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.

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.
