SOURCE: I have a invacare The joystick mk5 will not lite up batt. are new

Some chairs, like the M91 are a real bear to replace the batteries and connectors can get knocked loose in the process. First, using a voltmeter you need to see if the controller is getting power. On the DC setting, use voltmeter at the three-pin female connection at the joystick that is the charging port. The two pins that are opposite each other are the "hot" pins, and your meter should read about 25 volts, +- 2 volts. If its 0, there is a connection that isn't made from the batteries through to the controller, or the controller or joystick is shot. If you do have power to the joystick, then it's probable that the joystick is shot. A new one from Invacare is pricey, around $1,000.00 I have found a new site that can repair most makes. I have not used them, so cannot vouch for their work, but give them a call and see what you think.

If you don't have power, start at the terminals from the battery, and follow each wire back to the power control box, unplug and replug firmly as you work your way back. Check all fuses on the way. Then check all of the other connectors inside the chair, unplug, and reconnect again. Unplug and reconnect the wires leading into the power control box, and then restart chair. If no lights still, then the power control module is probably the culprit, but the address above fixes those too. The joystick and the power control module work together to make the chair operate safely. Good luck

The three light flash indicates a short circuit between the left motor(as you are sitting in the chair)and the battery. Check all the wiring from the control box to the motor and make sure it is not damaged in any way. If it is okay, you have most likely fried the left side motor. A new motor-gearbox assembly for this chair runs in the neighborhood of $1,400.00, or you can take the motor off and take it in for a full rebuild for about $250 or so. Unplug the joystick and remove the seat and cowl. Jack up the left side with both motors in gear. Remove the center nut cover and take off the nut holding on the wheel taking care to retain the key that slides into the groove on the axle. Disconnect the wiring plug to the motor and remove the six bolts holding the motor to the frame. Separate the gearbox from the motor and take the motor to a rewind shop for repairs. Reinstall and it should be good to go.

SOURCE: Has left motor error (3 blinks) checked

Hi. Your problem will be either the free-wheel lever is in the wrong position, or the motor has a stuck or worn carbon brush.
Good luck. Neil.

Ranch well the red flash indicates a low battery and the 5 flashes indicate a bad left brake. Now try charging the batteries until you get a green light on your charger then turn on the chair it shouldn't flash the red if the batteries are accepting the charge. If your batteries are 2-3 years old it could be time to change them. If Medicare paid for your chair then they will pay most of the repair costs. You can contact your provider for help or a service company like Roadrunner Mobility @ 1-800-467-2668 or Repair Xpress @ 1-877-581-3733. If Medicare did buy the chair then you are eligible for a new chair every 5 years and yours is almost 8 years old. Contact a local provider that you trust to check into getting you a new chair. Hope this helps you

The lights are flashing and it will not do anything. I plugged it in and it shows 2 red lights, 2 yellow , and 4 green . It is moving from left to right since I plugged it in an hour ago.


Make sure that you are charging the chair 12-14 hrs before driving. charge with the joystick on, make sure both freewheel levers are in locked position.

You are getting a motor error code. Check motor wiring and connection to the main control box. Motor may have gotten unplugged when changing the batteries.

What does 7 times flashing mean is wrong on pronto m91


Hello,

Seven blinks is most often the joystick. A Invacare Remote Programmer can be plugged in to the joystick to verify this.

I have the tdx sp and the wrench light is flashing 7 times what does this mean?


There is a problem with the remote joystick. Could be a bad connection or bad harness to the remote joystick. If harness is fine then the joystick has issues and needs to be replaced or rebuilt.
Try the 4-wire harness first.

My pronto m91 was flashing 5 times on the yellow led and after i resert it like you said it ran for a minuet and now it flashes 4 times on the bottom yellow led.


I am new to this request. Hope you have had your chair fixed by now, but in case not. If you still need help I really need more chair information. What joystick? Many different joysticks with different yellow lights. With a 4 or 5 blink it could be a motor or battery voltage problem.

Sometimes, out of the blue, when i snap on my M91 and touch the joystick, i will here a faint click and the power display will start blinking. the machine will NOT move. any ideas?


With the M91 the click you are hearing is the electric brake solenoid engaging and disengaging the electro mechanical brake. The display blinking probably indicates a brake solenoid fault code and right or left motor. Try working both brake levers back and forth listening for and feeling for smooth action. If the levers are bent and the brakes are not working a motor replacement is necessary. If you can identify the fault flash code you can determine which brake or motor is the culprit and use a DVM to verify the component failure.
