Invacare Supply Group 10" x 3" Foam Filled FlatFree Tires for the Invacare Pronto M71 Power Wheelchair () - Answered Questions & Fixed issues
I have an Invacare M71
No need to replace the circuit board just take a pencil eraser and rub the gold contacts to clean them making sure that you clean the residue after cleaning. the faceplate buttons have a metallic coating under the button and over time will wear off. You can glue a small piece of foil to the bottom off the buttons and the switches will work fine Since you have already purchased a new faceplate you can install it or you can glue foil to the bottom of the on/off button of the old faceplate and keep the new for later if you need it. Hope this helps you
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.
M1V R11 Joy stick blinks 5 times
I believe this fault code indicates a left parking brake fault. Check all the connections from the motor/gear/brake assembly on BOTH motors (sometimes the controller gets confused). Follow the wires from the motor to the controller and reconnect them all. Make sure the free-wheel lever is in gear by taking out of gear, and placing back into gear firmly.
Good luck.
My wife has an Invacare Buzz scooter - I have got
The Buzz breaks down into four pieces for transport. Electrical connections must be unclipped to separate it completely. It is possible that one of the connections isn't completely clipped together, so my first check (after you have made sure that you have it plugged into a working outlet!), would be to take it apart and then reconnect everything firmly. While you are at it, you should look for any other clip-connections and undo, then redo all of them. Even those that "look okay". Inspect the connections metal fittings for signs of corrosion or dirt that may be causing a high-resistance connection, and clean as necessary. Run you fingers along the wiring to check for any places that my have been damaged, breaking a wire connetion in mid-stream. Make sure the connections to the batteries are clean and free of any corrosion too. Be sure to check the fuses to make sure you haven't blown one, and also push in your circuit breaker. These sometimes trip while charging due to spikes caused by thunderstorms. If you do all this and it still isn't charging, you'll need to open the shroud at the head of the tiller and inspect the connections running up inside the tiller, and the connections going to the PC board located at the very top of the shroud where the thmb-paddles hook into the electrical system. There should be a fuse inside there too, so check that.
Good luck.
