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	SOLUTION
OF BEEPS
1	Low battery voltage	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.
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.
3	Motor wiring trip	The motor has a short circuit to the
		battery. Check all the connections and
		leads between the motor and the bat-
		tery.
4	Freewheel switch trip	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.
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.
8	Possible control system	A control system trip is indicated. Make
	trip	sure that all connections are secure.
9	Solenoid brake trip	The parking brakes have a bad con-
		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
		to the S-drive. This is usually caused
		by a poor battery connection. Check
		the battery connections.
