Unlocking Power Wheelchair Joysticks - Statewide Mobility

5 Jul 2014 ... Unlocking power wheelchair joysticks is essential to a power wheelchair owner. ... Many of you who use power wheelchairs do not fully know the hidden ... joystick, which is commonly found on Invacare power wheelchairs.

It seems to be a known issue. Is it the black disc by the axle in this image?

I would put a large hose clip around it. If you have the old one, you can probably get a replacement from Home Depot, or contact the company for a free one.

The squealing noise is probably a bearing either in one of the four smaller tires called casters. The problem will not likely cause a break down right away but should be checked by someone mechanically inclined or trained in power wheelchairs. I don't know what you mean by the chair being "forced". Need more info.
May have something to do with batteries.

If the chair is driving slower and batteries are new their is a recall for that joystick from Invacare. Invacare is replacing joysticks for free.

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.

single post, lift handle to rotate then pull up very hard!!! four poster lock is between knees release tilt back and remove

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.

First thing you must know is that the error codes are reversed on Pronto chairs with SPJ+ joysticks.
Only one year the M41 was made that the codes were correct. From approximately April 2008 to May 2009 was the only time a left error code ment left motor and a right code ment a right motor. Same for brake codes.
Brakes codes happen when the brake is out of gear, unplugged from the control brain or wire cut. Also from internal coil damage. Unless it's a wire you can reconnect you cannot fix the brake.

The M51 does not have a stability locking kit. The Invacare TDX SP has a gas strut stability locking kit that just had an extensive recall campaign associated with it. Please describe your issue in greater detail.
