Battery voltage
When the battery voltage is low, the 'battery gauge status'
indicator bar light, situated on the control console ( fig 11,
page 8 ) will flash one red bar slowly as a warning to recharge
your batteries. If the 'speed controller' detects a fault the
battery gauge/status indicator will display a number of bar
flashes indicating the nature of the fault.
For example, the controller will not operate if the speed lever
is not in the neutral position ( fig 12, page 10) when the
Scooter is switched 'on'. Return the speed lever to the neutral
position, when the Scooter will be allowed to operate normally
once again. This safety detection is indicated by a steady
rippling display on the battery gauge ( see also Fault Diagnosis
below ).
If your Scooter is turned 'on' but not operated for a set period
of time ( 15 minutes approx )the speed controller system will
automatically turn itself 'off' to conserve valuable battery
energy, you will note the battery gauge is switched off. It can
be turned on again by turning the on/off switch to 'off', and
then to 'on' again.
A reversing buzzer is provided for when you are driving in a
reverse direction. This is an important safety feature to make
other people aware of your change of direction.

COMMENT
Check speed pot wiring for open or short circuits.
Speed pot may not be correctly set up . Contact your
Service Agent.
Fault detected in main controller-contact Service Agent..
Fault detected in solenoid brake or connection to it .
Battery voltage at the controller is greater than 38
volts. Check condition of batteries and connections.
Suspect a charger malfunction.

The
Scooter's speed controller incorporates a
current limit thermal protection circuit which is activated when
the working temperature of the control unit exceeds a
predetermined safe limit.
The thermal protection is normally activated if the Scooter has
been working very hard, for example when you are climbing a
steep incline the thermal protection is designed to
automatically limit the current output to the motor to give it a
measure of protection in stall type conditions.
When the controller detects it's critical thermal limit you will
realise that the motor automatically slows to a reduced output,
when this condition is noted you should safely stop your
Scooter and wait for a period of time for the motor and
controller to cool before you proceed with your journey.
Please be aware this condition is not a fault, but a protection
method of reducing irrepairable damage to your motor; it
should also be noted that this condition will vary due to
ambient temperatures.
Faults with the main speed controller are rare ( see fig 28 )
Most faults on powered vehicles are associated with wiring
mis-connections due to a lack of maintenance or poor battery
performance due to charging errors.
If your
Scooter should fail to operate you will
be assisted in diagnosis and locating the area of the fault by
observing the number of segment flashes emitted from the
battery gauge status light on your control console.
If your
Scooter fails to operate and the battery
gauge status light is not illuminated, first check the points
aforementioned under 'FAULT FINDING'.
