a bad connection on the battery. Check
the connections to the battery. If the
connections are good, try charging the
battery.
2 Motor disconnected 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.

battery. Check all the connections and
leads between the motor and the bat-
tery.

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.
5 Not used
6 Charger Connected The S-drive is being inhibited from driv-
ing. This may be because the battery
charger is connected.
7 Throttle trip A throttle trip is indicated. Make sure
that the throttle is in the neutral posi-
tion before switching on the scooter.

trip
A control system trip is indicated. Make
sure that all connections are secure.

nection. Check the parking brake and
motor connections. Make sure all the
system connections are secure.
10 High battery voltage An excessive voltage has been applied

by a poor battery connection. Check
the battery connections.
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.
