When I turn the chair on, it will not move. The yellow wrench flashes 5times. I have moved the lever for free wheeling and still nothing. I have checked all connectors on they are just fine. Battery is fully charged also. When I move the joystick I can hear a clicking noise from under the seat. I'm thinking that is the breaking system but can't tell if both are working(clicking) or just one. The yellow wrench is telling me that it is the left side break. I don't know what else to do on it.
