INSULATION CONTROL PROCEDURE
When any trouble occurs, first inspect the truck insulation and its components, according to the following
procedure:
Truck insulation check
1. Disconnect the battery from the truck
2. Measure the resistance between the truck plug positive
and the chassis (in an unpainted point)
Standard: 10 MΩ or more
3. Measure the resistance between the truck plug negative
and the chassis (in an unpainted point)
Standard: 10 MΩ or more
Battery insulation check
1. Disconnect the battery from the truck
2. Measure the resistance between the battery plug
positive and the case (in an unpainted point)
Standard: 10 MΩ or more
3. Measure the resistance between the battery plug
negative and the case (in an unpainted point)
10 MΩ or more
Motor insulation check
1. Disconnect the battery from the truck
2. Measure the resistance between a phase and the motor
body (in an unpainted point)
Standard: 10 MΩ or more
3. Turning the rotor slowly by hand, measure the
resistance between a phase and the motor body (in an
unpainted point)
Standard: 10 MΩ or more
MOTOR WINDING CONTROL PROCEDURE
When any trouble occurs, check the state of the motors, following the procedure described below:
Motor phase continuity check
1. Disconnect the battery from the truck
2. Disconnect the three power cables
3. Check the continuity between the motor cables
Standard: U-V 0 Ω
V-W 0 Ω
U-W 0 Ω
