I have a lightly used jazzy 1122 power chair. i can't get controls to work properly. It will run in a fairly straight line on level floor or sidewalk. but on the ground or when a wheel hits any size obstacle you loose control and you can not control its path. It is also almost uncontrolable up any kind of incline. I need to use the chair outdoors and it just doesn't get the job done. Any ideas ?/

SOURCE: lights on hand control flash off and on and chair will not operat

There is a series of diagnostic flash codes associated with the controller. The diagnosis depends on which color and how many lights are flashing. If you post the combination, I can help you. Or you can download the Basic Operation Instructions of the Pilot Controller from the Pride website. The codes are listed on page two on the troubleshooting instructions.

Flashing lights indicates a fault. Here' the users manual which contains the fault codes for the flashing lights. Repost with more info re: the fault codes. Good Luck.

Also, make sure the charger is not plugged into the chair.

Look in your owners manual for the flash code anwser. Make sure when you hit the power button you only touch it for 1 sec not more. If you press the power button for more the 2-3 seconds you place the power chair in LOCK OUT mode. lights will flash and not power. also check your free wheel levers. one on each moter. Mike

When a chair sits for a long period of time ( four weeks or more) without being charged, the batteries die. To help you with the freewheel mode I would have to know what model of Jazzy it is.

SOURCE: chair no longer charges, no flashing or blinking, lights,

The number of lights that are blinking indicate what the problem is. Visit this site to locate the type on controller on your power chair and you will be able to see that the blinking lights mean:

Try to reset your manual brake release as this is a common problem.
If you continue to have a problem, contact your manufacturer or dealer for service. If your insurance purchased they power chair for you, they may also cover the cost of repairs.
Good luck!
