Alarm sound all the time when switch on
Hi, that normally happens when the scooter is in freewheel mode, now double check the lever located at the rear, okay having done that , disconnect the axle from the main frame, check the connection here are clean and touching , if it's a plug remove the plug stray in some contact cleaner , refit making your it 's a tight fit, Still got the problem then check the micro switch located near the freewheel lever , normally located on the brake mech , make sure it connecting when the freewheel lever is moved.~RegardsGeWiz.
Rubbing noise rear end but not all the time...
Hi.Most scooters use a steel key in each rear hub to drive the wheels. These often get noisy. As the wheel turns the weight is put on the key and then comes of as the wheel keeps turning making a noise each revolution of the wheel. To repair remove the rear wheels and wipe a thin smear of grease onto the axle and key. This will reduce the noise. Hint, loosen the bolts holding the wheel on before raising the rear end to remove the wheels. If you place a support or block of timber under the machine, be careful of the motor brush holders.
Other noises could be gearbox gears worn.
Good luck. Neil.
Scooter moves approx 10 feet then stops led flashe...
Hi. 8 flashes is a fault code for a motor fault. It will be either worn brushes in the motor or faulty connectors to the motor. This fault code means that there is no circuit through the motor. Probably time to overhaul the motor. Most mobility scooters have plugs and sockets that are really to small to carry the amount of current that they do. Because of this, they sometimes fail.Good luck. Neil.
What flash codes mean
They are diagnostic codes to help troubleshoot a possible problem with your wheelchair. The lights blink in patterns. You have to count the number of blinks and what color they are.
24v dc motors can it run at all with 12vdc
Sure. Just slower.
If you remove the motor from a power wheelchair to use in other applications keep this in mind; these motors are designed for PulseWidthModulation Speed Control (apx. 10kHz) with a feedback control to keep the speed more consistent. Feedback and pulsing is key to power and efficiency. If you run them at 12 volts without a pulse control the current to power output is much higher and the I*I*R (I squared times R) losses are higher - dissipated as heat. The motors will run very hot under a load with DC that isnt PWM'ed.
If the use/cool down duration is short you should not have issues.
My Invacare TDX SP has died on me and someone told me of a trip switch on the batteries..Anyone know where this switch is as all I can see are bolts and metal?

First check if you have power present at the charging port. If you have power (24 volts) then the batteries and wiring are not the issue. If you don't then check the battery post fuses. These are "L" shaped brackets with a white square fuse held on the positive post with a through bolt and nut. On older chairs these are known to become loose and or blow just when you need power or stop suddenly.
Also check the big Anderson connectors at the power point at the end of the battery box. Check for solid connections. If there is 24 volts here to the control box, next check the controller connector.
If there is +24 at the controller connector but 0 at the joystick charger port you have big issues. Either the traces connectors in the controller are fried or your joystick has major issues.
Is it possible to reverse the drive lever on the
Hi Mark.
Reversing the polarity:There are 3 wires on the Wig Wag Assembly. (reverse the wig-wag function) simply de-solder the 2 outer wires & swap their position & re-solder.I would seek a price for doing the job from an approved scooter repairer,unless you are comfortable doing the job yourself.I hope this has helped,Colin
Wiring
most manufacturers will NOT supply you with that, very difficult to get, FDA has strict guidelines on who can repair and maintain power chairs. what is the problem with the chair
