The small click noise is the parking brake releasing to allow you to drive. the flashing is called a flash code that will give you an idea of what is wrong. count the amount of lights flashing this would indicate the problem. Post the amount of lights flashing and some could give you the meaning of the code.

You would need to remove both covers top and bottom of the console holding the throttle pot. Typically, there are 4 or six screws holding the covers. The throttle pot is attached with 2 screws and has 1 electrical plug. The throttle lever on the end of the throttle pot shaft usually is held on with 2 Allen wrench set screws.
Before replacing the part it can be tested using a digital voltmeter.(procedure is described elsewhere).
Obtain the correct replacement part by searching by Model and serial number and part description. The manufacturer website is a good starting point for parts

What are number of lights and colors? Check motor connections to controller. Is it freewheeling?

Sounds like the inhibit function of the chair has been damaged. This function will not let you move the chair while charging. If Dad doesn't have the charger off when plugging in to the chair or removing it it can short out the charger port causing your problem. Unfortunately the only fix is to replace the joystick/controller. If Medicare paid for Dad's chair then they will pay for most of the repair costs. Contact the provider that brought Dad's chair and ask if they can order a new joystick for you Hope this helps

Has your scooter been sitting idle for several weeks, or has it been connected to the charger 24 hours a days for a long time? If so, the batteries may have become damaged and will give you enough power to turn the controller on but not enough to make the motors run.
If the lights come on and are steady, the manual brake levers are in the drive position and the chair still will not move, I recommend replacing the batteries. If anything else were wrong, either the lights would flash or not come on at all.
I hope this information is helpful to you, good luck!

Make sure that your drive wheels are engaged and the power chair is not in the freehweel position (so it can be pushed).

8 lights flashing how can i fix it?
