Question about Invacare Pronto M51 Power Wheelchair
Eduardo After using your chair and the battery level lights are down with yellow or red lights showing just plug the chair into the wall socket and let er rip. Now really after using your chair during the day and you are ready for bed just plug in the charger and let it charge over night. In the morning unplug the charger and you should be set for the day. If you don't use the chair everyday always put it up with a full charge and about once a week plug it in and let it charge overnight. Never leave the chair plugged in all the time and never leave it for more that 24 hours. The charger has two lights on it one red and one yellow or green that are hard to see because they are under the rear cover. When the chair is fully charged the yellow light turns green and you can unplug the charger and you should have a full charge. Hope this helps you

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.

Three lights flashing on your chair indicate a left motor fault. Make sure that all of the connections inside the shroud are tight by physically testing them. If all of the connections are good, and the fuses are good, then it's time for a trip to an authorized repair facility. Here is a link to the M51 owners manual if you haven't one. Page 24 has the fault code guide.
The controller monitors all of the functions on the chair, brakes, motors, joystick, charger etc. The three flash fault indicates an "open" circuit. Open, like a switch or blown fuse is open, or a wire is cut or burned in half, or a connector is unconnected, or partially connected. The latter is what you are hoping for. Wires burned in half is the usual cause for a motor fault, and with powerchairs, is usually the result of the chair getting stuck in or against something it can't get out of and the operator over-amping the motors. Motors do, just go bad sometimes, for no reason. Very rarerly, however.
You can also check the brushes on the motor too. There's two quarter-sized black plastic screw-plugs on the ends of the motor opposite each other. Unscrew them and examine the brushes. The springy coils should be springy. Overheating can cause them to be brittle, or even burned in two. Check the lench of the brush, the dark rectangular cube at the end of the springs. It should be curved and polished at the end, and a little over a half-inch long. If it is near a 1/4 inch, it needs replaced, or if there is any evidence of overheating, replace. Good luck.

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.

The 9 flash error code indicates a communications fault. The communication fault relates to the communication between the joystick and the control module. The joystick on the arm mount is connected to the control module in the base. When there is a break in the wiring of this wiring harness, also called a bus cable, a fault occurs. This trips the computer and the computer sends out a flash code to the joystick. Simply stated there is a broken or pinched wire between the joystick and controller. Look physically at the wire and check for cuts, breaks or pinches. The best short term repair is to repair the broken wire with solder and heat shrink or tape. You can also use **** splice connectors and tape. The best long term repair is to replace the harness with a part available from Invacare. The most definitive way to diagnose this problem is to read the fault log of the controller using a hand held programmer available to dealers and certified technicians. The number and type of fault codes logged in the controller is another indicator of which
component(s) has failed. Hope this helps.
