Electric Drive Motor
Figure 33 Figure 34
The electric motor that provides power to the rear wheel is a
450 Watt (300 Watt on earliest models), continuous cycle
motor, connected to the batteries via two lead wires. Typically,
the motor either works, or does not. After you are confident
that the batteries are accepting and retaining a full charge, it is
easy to test the motor.
With the deck off of the PowerBoard, remove the battery leads
from the controller, and from the batteries. To ensure the drive
motor works, connect the motor leads directly to the battery
terminals. This effectively bypasses the circuit board, and sends
power direct from batteries to the motor.
NOTE: Attaching lead wires to battery will create a spark.
NOTE: Newer models do not have lead wires form the motor
that are detachable from the circuit board. Instead they use a
coupler plug to connect to the circuit board, (see fig. 35). This
make testing the drive motor a little more difficult. On these
models, it is necessary to “jump” from the plug attached to the
motor side of the lead wires to the batteries, but is effectively
the same procedure as described above.
A special tool is available that has the proprietary plug to attach
to the harness and battery terminals on these models and can
be ordered as part# 31655.

If the motor does not turn when tested this way, it is defective and must be replaced as an assembly. Removal of the motor is
made simple by the two sub-frame pieces on either side of the frame. Removal of the bolts on chain side only will allow the
removal of the motor.
