Bi-speed Controller Connector Voltage
1) Connector Voltage
1. Disconnect the 16P connector (1).
2. Turn the main switch to ON position. It is not necessary to run
the engine.
3. Measure the voltage with voltmeter across the h terminal (4)
and g terminal (3). If the voltage differs from the battery voltage,
check the fuse, wiring harness or ground condition.

1. Remove the connector for bi-speed valve.
2. Jack up the rear wheels and shift the front wheel drive lever to
OFF position.
3. Start the engine and turn the rear wheels as following condition.
• Range shift lever: 1
• Cruise control lever: 2 notches
• Engine speed: around 1000 min
4. Steer the front wheel to the left or the right 0.61 rad (35 °) or
more.
5. Measure the voltage across the following terminals and chassis.
If the voltage differs from the factory specifications, check the
wire harness.
CAUTION
• Be sure to disengage the front wheel drive, when checking
the voltages with rotate the rear wheel.
