No drive and the Status indicator flashes
(3, 2) code
1.Check if brake connector is plugged into J3 header.
Switch power off and perform the brake coil
continuity test. If the reading does not appear
correctly check for open or shorted wires. If they are
good replace the brake assembly.
2.Switch the power on and perform the voltage brake
output test. If the reading does not appear correctly
one of the following parts could be faulty:
- Cable that connects the controller with the
Front board
- Controller
- Front board
Excessive heat on the brake body The brake assembly is mechanically damaged.
Replace the brake assembly
When turn the cap motor knob to
release brake the horn doesn’t sound
and the driving is not inhibited
Perform the micro-switch test If the micro-switch
operates properly replace in the follwing order: Front
board, cable between Front and Controller board and
final the Controller.
7. THE MOTOR HARNESS
How to check the controller output? Measure the voltage between controller’s
terminals M1 and M2.
When is selected Forward direction M1 will be
more positive than M2 and the voltage read is
approximately 1.5V less than the total battery
voltage. With the throttle bar fully depressed in
Reverse you should see a negative reading of
about 60% of the total battery voltage.
How to connect the gear-motor? Connect Yellow cable to M2 controller’s
controller terminal and Brown cable to M1
The controller output appears to be normal but
the performances are lowered or the motor
doesn’t run any more.
Disconnect the yellow and brown cable from
the controller side. Turn your meter to an ohm
or resistance scale. Place the red probe of your
meter on the yellow wire’s terminal and the
black probe on the brown wire’s terminal.
Take the resistance reading across the motor.
A reading between 0.3ohm and 2-4ohm should
appear. If the reading is higher than 4 ohm
replace the brushes. DC brush wear is the
result of mechanical friction and electrical
corrosion.
If the reading indicates an open circuit
armature try first replacing the brushes. If
nothing happen replace the motor.
The driving speed forward direction is less
than the speed in reverse direction
Check and correct the connections at M1 and
M2 or wiring to motor. This problem occurs if
the cables yellow and brown are reverse
connected.
