Twice now, within 6 months, the cable that goes into my joystick on my Nturon R51LXP has shorted out and left me stranded. over the summer, after the cable was first replaced, my joystick encasement was actually heating up some. my repair guy says he has no idea what's causing it to short out, but it could be a hundred things. I called Invacare and their tech support pretty much said the same thing. seems like everyone's just putting a band-aid on the problem by just replacing the cable that connects to it - any ideas what it could be? could the joystick box itself be the problem? also, the back wheels are emitting a slight grinding noise and the motors are running kinda hot too. and seriously, the chair is only 2 and a half years old! any insight would help, especially since the chair is still in the shop! thanx - jt

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.
