Jet 3 chair seems to go left when you move joystick right and visa versa, thanks-B

Something between the batteries and the motors and joystick is interrupted. Recheck fuses and connections.

Did you cross your connectors? Is the joystick gimbal backwards?

If chair has a tilt, recline or lift seat on it it may be going into lock-out mode on its own due to a limit switch fault. If you don't have any of these options then I suggest you remove the joystick, controller and any wire harness between the two and send them to a shop like mine for repair.
The usual lock out light chase is from left to right - not right to left so this is suspect of a different issue.

Do all of the speed lights flash at the same time or do they ripple from left to right? If they ripple from left to right the chair is in lock mode and you can use the unlock procedures from my tips to unlock. If they are all flashing at the same time you have an internal joystick problem and the joystick needs to be replaced Hope this helps

The chair should have a meter on the rear panel where the 9 pin connector for the joystick plugs into the chair when you plug in the charger cord the meter should move up and the lights on the joystick should flash indicating the charger is plugged in. When the chair is fully charged the meter should read zero or bounce up and down. Hope this helps

cali check that you don't have the chair in freewheel. The levers are on each motor at the rear of the chair. Make sure they are both in drive position. If they aren't in freewheel then you have another problem. Make sure that the charger is unplugged from the wall and that you get all of the battery level lights lit on the joystick when you turn it on. If all seems ok and you still get no response then the problem could be the joystick or the power module and only a tech will be able to diagnose the problem. If Medicare paid for your chair then they will pay most of the repair costs contact your provider or a repair service like Roadrunner Mobility. Hope this helps you

RB Are the lights giving you a flash code ie: 4 flashes pause four flashes etc or are they all flashing with no pattern? Make sure the chairs freewheel levers are in the drive position then turn it back on to see if they still flash. If the lights are scrolling from right to left then the joystick is in lockout mode. let me know what you find and maybe we can figure this out. Hope this helps you

The chair is in lock mode. To unlock, turn on, when the lights start to scroll, push the joystick forward and keep it there until you hear the beep. When it beeps, pull it back and wait for the beep, once the beep sounds let go and listen, if you hear a high pitch beep, success. If it doesn't work the first time, just do it again. Sometimes it may not work right away but don't panic, just follow the steps again.

hold joystick back, press on button, move joystick forward, then let go.

I just had the same problem with my uncle's power chair. The number of "blinks" indicates a problem code to the technicians. My chair needed the joystick control assembly replaced. Once replaced, evrything was back to normal. 'Not a cheap fix but much needed. Good luck my friend!!
