rated by a short delay between each sequence, and refer to the table below.

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 battery.
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 driving.
This may be because the battery charger is
connected or the seat is not in the driving
position.
A throttle trip is indicated. Make sure that
the throttle is in the neutral position before
switching on the scooter.
A control system trip is indicated. Make sure
that all connections are secure.
The parking brakes have a bad connection.
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.
