I have a jet 3 ultra motorized wheelchair and the rightside tire wont move forward or backwards,also the motor is very hot.what could be causing this?

Question edited for clarity.

You have a dead short somewhere. You need some electrical knowledge and a digital multimeter for testing. Take all the covers off. Look for wiring that has rubbed through and touching or melted. Disconnect one of the motors and replace the fuse. If it still blows, reconnect that one and disconnect the other motor. If one motor doesn't blow and the other does, you know you have a faulty motor. If neither stop the issue, then you move up to the controller and look up there. With a meter you can check for shorts within the motors, as well as grounds.

Or just take it to a Service Centre and have it repaired and serviced properly.

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

It seems that the joystick contacts are burnt.

bad motor brake is number one suspect located on back of motor or motor brushes or motor itself call 1-800-800-8586 jazzy tech support

check the motor brushes if they are 1/4 inch or less replace them. Next, after driving the chair for a while check the motor casing near the brake assemblies on the rear of each motor if the casing is hot then you have a sticking brake pad or pads and this can cause the excess battery drain. If you have sticking brake or brakes unfortunately the whole motor assembly will have to be changed Hope this helps

you got something silly going on there. about the only thing that would cause this is a problem in the joystick controller. take it to a local store that has a joystick programmer and get it fixed for cheap.

one of the motors is bad or has bad connection. try raising the chair so the drive wheels are off the ground (free-wheel) turn power on, push joystick forward and watch for drive wheels to turn. the one that wont indicates a bad motor or connection.

Check that you don't have the charger cord still connected or the motor disengaged.

Sounds like your motors are gong out. You`ll need to get to a reputable dealer for further diagnosis.

Do they flash in series? Like ten flashes then a pause then ten flashes?
