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?

Owners manual for TDX SP link above.
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
4 geen flashes and 1 red means what?
You can visit this website to find answers on what the flashing trouble indicator lights mean: http://www.pgdt.com/scenter/diagnostics/diagvsi.html
Locate the page that has the controller used on your power chair/scooter
and count how many lights are flashing to diagnose the trouble. If
your insurance purchased the power chair for you, they may also cover the repairs; contact them for information.
Good luck!
What would cause the display of the message "MPJ
This display message can be caused by some of the following:
Joystick out of neutral at start-up.
Bad or broken joystick gimble.
Bad or uncalibrated joystick gimble.
Bad wiring harness or connector from joystick
Internal joystick electronic component problem.
Bad communication chip in joystick.
Incorrect programming of the joystick
The most direct test is to run the joystick gimble in circles and forward, back, left, right, feeling for bad or dead spots and uneven action. Look at the position in neutral: left,right, forward ,back should be in alignment. A bad gimble is inexpensive and straightforward to repair.
Inspect the wiring for cuts, pinches and bad pins on the mating connectors.
With a hand held programmer (HHP) plugged into the main harness or charging port you can read the fault log. That way you can make a definitive diagnosis. You can also calibrate the joystick with a HHP and adjust the programming parameters.
If the chair powers up but the batteries are low you can get unusual electronic problems so test the voltage with a digital voltmeter. Voltage should be between 24 and 26 volts. It is possible but less likely you have a bad controller. Again, the HHP will read the register of all faults to help you determine the cause of your problems.
Check the obvious first and then swap out the joystick with a known good working one to determine definitively that the joystick is your problem. Hope this helps.
Not holding a acharge and
Hi and thank you for using fixya:
This problme is caused by a bad battery. How long have you had the scooter with the same battery? Is time to get a new battery that one can not hold batteries any more. Go to google.com and search for the model and battery.
Thanks
I bought a used pronto m51. What is up with the
Jhester Well You just need new batteries. Does the chair come on when you diconnect the charger and does it move? If you don't have all the battery level lights lit up when you turn it on then the batteries are too low for the charger to pick up. No lights no power New Batteries Hope this helps
Heavy steering on my s/h sungift 200,ok when
Hi Dave. I have had a few scooters that have had this problem. Most of them had the bearings tightened up to tight. Either the bearings on the steering column, or the bearings in the left or right stub axles. Just loosen off very slightly will help. Make sure that there is not too much movement in the bearings after adjusting them. Also give all the linkages a bit of a lube.
We are Invacare sales and service agents here in New Zealand, but I have never heard of this model.
Good luck. Neil.
Clicking, first noticed on carpeted surfaces.
Clicking from the tires is usally due to one of two things. First, check to see that the nuts holding the wheel onto the axle are tight by removing the plastic cover and tightening them as hard as you can. Drive and see if it quit clicking. If not, check the air in the tires; they should be kept at the stated range on the tire. If they are foam-filled, flat-free tires, these can often click when the tire chages against the wheel. It doesn't affect the safety of the scooter but can be annoying. Spraying some WD-40 around the rims inside and out will often clear it up. If not, you'll need to pull the tire and tighten the 4 bolts that hold the split-rims together.
