Nutron r51
The age of the Nutron is not the issue, unfortunately. I have seen problems with this model right out of the box. The joystick control is the first area to check. If you have to compensate the joystick so far to the right to correct, you may have a damaged joystick gimbal. You may also have a bad joystick control board or damaged connecting cable to the controller on the bottom frame. Check for damaged, pinched loose or disconnected wiring below at the controller module. With a folding frame it is easy for the wiring to be become damaged or dislodged. Check for cut damaged pinched wiring at the joystick. With a handheld programmer (dealer) you can check for error codes in the fault log. With a poor performance issue there may not be a fault recorded in the log of the computer module. I have also seen these motors fail prematurely. In this case your left motor is dragging or weak causing the chair to go left. With a programmer (dealer tool) you can compensate for this while waiting for new parts(temp fix). Sometimes the motor brushes burn or hang up. Try blocking up the chair off the ground and run it no load to check for motor performance and unusual sounds. Check for joystick dead spots or uneven action. A quick check of the joystick would be to plug in a known good one at the dealer to test. With the chair blocked up try tapping the motor housing to see if the performance changes. Inspect the brushes if you have access to the brush caps.Check the obvious first, plugs, pinched, broken wires and partial plug disconnects and corrosion. If you have a voltmeter you can do some checks on the motors and brakes. Going from memory, the motor leads large black and large red should read zero ohms with the 2 small white wires for the brake reading between 60 and 70 ohms. Check the Invacare manufacturer website for exact specs and technical info for this model.
Hope this helps.

Twice now, within 6 months,
Ok the heating up part means that there is something wrong with the power ciruit itself, chances are something is outputting more power than it should, disconnect the joystick box and see if the motors heat up, I'm betting it wont. The reason being that the joystick box has several switches in it, 1 or more of them is feeding power back to the ground which then transfers it to the motor causing cavitation in the motor circuit it self, e.g. Forward and backward at the same time, but since u push foward that gets more power so it moves or vice versa., Once you verify the above I dont think you need to replace the entire box, but clean the contacts or change the switches, only then change the box if the problem persist.
Now 1 symptom of the above is a reduction in power (the chair now isnt as fast as it should be)
Fixing the above will fix all on that. Please let me know after you have the shop check these things out.

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.

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

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
