The free wheel levers have got to be in drive mode. if one is in drive and the other side is not then the chair will try to go in circles. So if the right side free wheel lever is not in drive position then the chair will try to drive to the right because the right motor is not turning the wheel. The wiring to the right motor may have become disconnected.

The chair is more than likely in free wheel. There are two levers under front of the seat (yellow). Pulling them forward should place the chair in freewheel and pushing the levers back should place the chair in drive. Once in drive mode, turn power on to reset joystick.

Have you completely disengaged the wheel locks? Check for worn wheel bearings.

Each wheel is run by a separate motor. This looks like either bad controller box, or bad motor. If it starts out working fine, then the one wheel stops after a short period of time, then it is probably a controller at fault. However if the motor is overheating due to mechanical binding such as a brake failure (the parking brake) or lacks lubrication causing excess power consumpltion, then the controller will shut down at some poiunt to avoid damaging itself and/or the motor. have a helper put the chair up on cememnt blocks, or woodne boxes etc, so you can observe it running. Listyen to the motor by doing left full and right full turns. The motors should be equally quiet and run at the exact same speeds. Dragging noises indicate a problem. be sure your parking brakes are disengaged. Now with the chair off, rotate eaach wheel by hand. They should need the same amount of force to move. if the bad wheel is harder to turn then it may need replacing or has bad brushes, brakes binding or in most cases dried up grease in the gearbox.

Your version has a Dynamic Controls model controller and joystick.
Unplug the charger and engage the motor/brake lever so the chair is no longer in free-wheel mode (con't push by hand)
Turn the chair off, wait 5 seconds, turn the chair back.
If chair still does not run and your wrench is flashing you have a problem. Count the wrench flashes - the flash count indicates the error detected. 3, 4, 5, and 6 flashes indicate and error with the motors.
3=Left motor fault
4=Right motor fault
5=Left brake fault (may not be engaged)
6=Right brake fault (may not be engaged)
Any other fault code usually means the electronics or wiring is bad and not worth fixing.

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

Hi Jack
Sounds Like all you need is for a technition to program you chair. They can do an adjustment to compensate the different strengths of each motor and make the chair run straight Also to improve the turning speed adjustments. Programer is a P&G PP1


Good Luck

You may want to check the bearings in the casters, that can cause a scrubbing noise and cause the chair to not turn well.

If there is a chirping noise, that may indicate a motor failure. There is a left and right motor, so if one is not working well, it can cause the power chair to not drive straight.
