I am trying to get a Revo mobility scooter to work, the lights work and power indicator shows there is power, but the scooter will not move forward or reverse when you press the lever, what do I check

SOURCE: Forward/Reverse switch not working Revo Pride

Could it be in free-wheel mode. Most Prides have a pull up knob at the rear of the scooter.

You can try to do this with the cover off, just in case it is not seated properly and holding the lever from fully engaging. The actual swithc is a small microswitch down at the brake, and it can get dirt in it and that will stop it from working, or it may even fail, and need to be replaced. So I would:
1) try it woth the shroud off the motor using.
2) look for dirt around the switch.
3) take a paperclip and jump the scooter side of the switch to bypass the microswitch on the scooter, be careful not to short the jumper to the scooter frame.

Let me know how you make out.
