Trouble Shooting Guide
Your scooter is fitted with a self diagnostic controller that will give a sequence of
audible beeps when an error is detected to help you, or the authorised service
agent, determine the drive electronics fault.
Should you switch on the scooter and hear the beeps note the number of beeps,
separated by a short delay between each sequence, and refer to the table below.
NUMBER POSSIBLE CAUSE
OF BEEPS
1 Low battery voltage
2 Motor disconnected
3
Motor wiring trip
4 Freewheel switch trip
5 Not used
6 Charger Connected
7 Throttle trip
8 Possible control system
trip
Solenoid brake trip
9
10 High battery voltage
SOLUTION
The battery needs charging or there is
a bad connection on the battery. Check
the connections to the battery. If the
connections are good, try charging the
battery.
The motor has a bad connection.
Check all the connections and leads
between the motor and S-Drive. Check
the position of the freewheel lever.
The motor has a short circuit to the
battery. Check all the connections and
leads between the motor and the bat-
tery.
The freewheel switch is activated or
the manual brake disengagement
mechanism is operated. Check the
position of the switch or lever and all
connections between the switch and
the S-drive.
The S-drive is being inhibited from driv-
ing. This may be because the battery
charger is connected.
A throttle trip is indicated. Make sure
that the throttle is in the neutral posi-
tion before switching on the scooter.
A control system trip is indicated. Make
sure that all connections are secure.
The parking brakes have a bad con-
nection. Check the parking brake and
motor connections. Make sure all the
system connections are secure.
An excessive voltage has been applied
to the S-drive. This is usually caused
by a poor battery connection. Check
the battery connections.
