Test 9. ELECTRIC MOTOR BRAKE
Description:
The electric motor brake is a 24-volt electromagnetic disc brake mounted between the drive
motor and the primary reduction gear case. The brake is controlled by the speed controller
logic. At what times the brake is applied or released is dependent on the controller programing
and will vary depending on the model vehicle.
Operation:
B+ is supplied to the brake when the key switch is turned on. When the control logic determines
that it is time to start, it provides B- at 24-volts through pin #9 on the logic card connector.
Testing:
Place the forward and reverse switch in the OFF position, turn the key switch OFF.
Rotate the drive wheels to confirm the brake is engaged.
If the brake is engaged then skip ahead to 9.1.
If the brake is not engaged then:
Disconnect the electric brake harness connector and repeat the test.
If the brake is still not engaged then:
•
Remove the brake and repair or replace the brake as required. Stop trouble shooting here
and repair the problem. When the repair is completed, completely retest the vehicle before
lowering the drive wheels to the ground.
If the brake engaged after the harness was disconnected then:
Inspect the harness for shorts.
Stop troubleshooting here and repair the problem. When the repair is completed, completely
retest the vehicle before lowering the drive wheels to the ground.
Test 9.1
Close the seat switch, turn the key switch ON, place the forward and reverse switch in the
FORWARD position, depress the accelerator pedal to engage FS-1 only (creep speed).
Rotate the drive wheels to confirm the brake has released.
If the brake released, then the brake system is working and no further testing of the brake
is required.
If the brake did not release, then perform the following tests:
