When I turn my wheelchair on a service indicator light at bottom of joystick blinks 9 times. How do I fix this?
My wheel chair has been charging, but when I turn it on the power indicator lights come on briefly, then a service code light blinks 9 times. How do I repair this problem?

The M51 could have the motor clutch levers in the free wheel/push mode and the joystick will not blink if this is the case. Make sure that the chair cannot be pushed. If it can be pushed it means it is in free wheel and you need to lock the motors in gear.
If it is in gear and the joysticks green light does not change color or blink it could be that the joystick is bad. When nothing happens and the lights don't blink when you push the joystick knob the chairs controller basically isn't recognizing the joystick movement.
Time to have the joystick repaired or more. Have a technician look at it.
A flash code of 9 indicates a communication fault. What this means is that there is a lack of communication between the joystick and the other electronic component, the controller module. In my experience, the usual culprit is that the charger plug makes bad contact inside the joystick housing causing it to heat up and burn. This can cause components inside the joystick to burn out. The other more common problem is that there is a break in the 4 wire harness going from the joystick down to the controller in the base. Sometimes it is just a matter of unplugging the connector, cleaning it, and pushing it back in. In other cases, the wire has been cut or broken along its length. Look for cuts along the black covering of the 4 wire harness (connecting cable)and twist and tape or splice and solder to repair the wires. These connecting harnesses are so inexpensive it is usually easier to replace, however a quick splice can get you going temporarily. If you smelled burning that would be an indication that the joystick assembly has burned out and I would replace that along with a new harness (connecting cable with a plug on each end) to the base electronic module.
The connecting cables have always been a weak link in this design and have had a history of failures over the years. For this reason I replace both the joystick assembly and connecting cable when servicing. Hope this helps.
7 Flashes indicates a joystick trip. Turn off your chair, ensure the joystick is in center position without anything touching it and turn on chair. This should clear the 7 flash code.
This problem is quite common amongst power chair users. It typically occurs when something is pressing against the joystick as you are turning the chair on.
Typically when a joystick flashes 9 times, it indicates there is a problem with the solenoid brake(s). I recommend contacting Pride Mobility for a Certified Technician in your area to look at this chair.
This problem may depend on which main controller your chair has fitted. It should be a Penny & Giles GC controller. US versions should have a GC3 whilst here in the UK, it would be fitted with a GC2. However, the diagnostic flash codes for these two controllers should be the same. The reason im slightly confused is that you say 5 flashes mean your charger is connected at power up, when in fact it should be a Right Motor Wiring Fault. 9 flashes is indeed a Solenoid Brake Fault, or in other words, the wheelchair is in 'Free Wheel' as you have described. Therefore, IF your controller is in fact a Penny & Giles GC, 7 flashes would mean a Joystick fault. There is not much you can do to diagnose this other than checking connections between the Joystick and main controller. If these are OK, it is likely that a new Joystick controller will be required as having these fixed is usually not cost affective. Hope this is of some help to you.
the 7 lights indicate a joystick problem which means the joystick/controller will have to be replaced since there is no self repair fix Unless you can locate a good used joystick/controller for cheap (around $600.00 rebuilt) I would return the chair and get my money back Hope this helps
The problem is bad communication between the joystick and the conroller or power module. By replacing the jostick cables you will see if that fixes the problem. Check with your provider (where you got your chair) to see if they have an extra joystick cable or can loan you one from a chair that they might have. Now there are 2 cables one from the joystick to the base of the chair and one from the base to the controller either could be bad but try the one to the joystick first Hope this helps
I just had the same problem with my uncle's power chair. The number of "blinks" indicates a problem code to the technicians. My chair needed the joystick control assembly replaced. Once replaced, evrything was back to normal. 'Not a cheap fix but much needed. Good luck my friend!!
