(B) Main Switch (CABIN Type)
Main Switch at ON Position
1. Turn the main switch ON position.
2. Measure the resistance between the terminal B and the terminal
AC.
3. If 0 Ω is not indicated, renew the main switch.

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 between the terminal B and the terminal
AC, and between the terminal B and the terminal ST.
3. If 0 Ω is not indicated, renew the main switch.

Connector Voltage
1. Measure the voltage between the terminal B and chassis.
2. If the voltage differs from the battery voltage (11 to 14 V), the
wiring harness is faulty.
