Pronto m51 electric wheelchair yellow wrench light blinks 8 times

SOURCE: How do I charge My Pronto M51 motorized wheelchair?

I also have a Pronto M51 and use it daily. I have found though by leaving the charger plugged in over a weekend, it reduces the battery range and does not come back to normal until I use it for a week and charge it nightly. You can overcharge the batteries because the charger does not shut off entirely. I have monitored this with my meter.

Take your drive units both out of gear and put them back in that will reset the computer and it started mine working again.

SOURCE: tool; light blinks 9 times battery is charged

the batteries were dead

SOURCE: control box on pronto m51 wheelchair don;t work

When you say "control box" I assume that you mean the joystick. If there is no power to the joystick be sure that the batteries are fully charged and be sure that they do not need to be replaced, also be sure that the cables were not put on wrong. If all that checks out then be sure that all the cables are tight.

If all these do not solve the problem then you need to have the joystick tested.
