Invacare Pronto M51 Power Wheelchair - Page 5 - Answered Questions & Fixed issues

recheck your polarity on the batteries carefully, i've done it for 15 years and the factory makes it complex sometime i connect backwards initially

should be one on each batt. they are to prevent over amping the electronics and/or if batteries are installed wrong, polarity wrong, to keep them from damage or worse.

why did you change the batteries, did you verify that it wasn't the charger in the first place, sometime the charger will appear to charge but actually isn't. put a meter on one battery then plug in charger if voltage goes up charger is good if not look for loose connections and or bad charger.

There are two levers, one for each motor, you have two. Depending on model either right under your knees (M51) usually, or under the rear, near the back casters. Typically black rubber on a metal rod. Move both in opposite directions, either both out, both in, or some types, both up, or both down. Sometimes they need wiggling, turn the chair OFF then try moving it in each position, (both in or both out). Google the manufacturer, your case invacare, they have detailed instructions there.

Hi.Sounds like your batteries have sulphated plates, this happens when they sit for too long without being used. Your machine is a 24 volt system, so it needs both batteries to be working.You might be able to get a bit more life out of the batteries.
Try removing both batteries from the machine and connecting a light bulb across each battery and discharging them until they are flat.
Then using a 12 volt charger, ( not the charger for the machine, which is a 24 volt charger ), charge the 2 batteries in parallel. Sometimes it helps to charge them up the wrong way for a few hours, then discharge them again with the light bulbs. After this charge them again in parallel with the 12 volt charger, this time the correct polarity, a leave on charge for 12 hours.
You might have to repeat the charge, discharge cycle a few times.
The batteries will accept a charge after a bit of this, but they might not be as good as new batteries.
If you are unsure how to do this, get some help from someone who can do the work safely.
Good luck. Neil.

If you have made sure that the freewheel levers are in the drive position and after turning the power on and you are still getting the barke error then the motor and brake assembly will have to be checked by a tech and possibly have to be replaced There is no self fix for your problem Sorry Hope this helps you

Sure they will but according to MK batteries good AGM atteries will perform just as well and for less cost. And thats probably why they told you that. They don't want to incur the higher cost because Medicare will only pay so much for the replacement batteries. Hope this helps you

Leave the charger cord plugged into the back of the chair and wrap the cord around the right armrest near the joystick. You can then plug it into a power strip located near your bed from the seated position. It won't hurt to have it near where you can reach it Just make sure that its secured when not being used and won't fall off the armrest Hope this helps

Hi,

It seems like one of the motor disengaged. There are some other possibilities like

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

The error code means one of three things. First it could mean the batteries did not charge up at all. Next is unlikely ,but it also means too high of a charge voltage. The code also comes on when the charger is plugged in to charge and you turn the joystick on. The chair protects itself from driving off with the charger cable plugged into the wall outlet. One more possibility exists, the onboard charger could be bad and bad batteries. You need to have a trained electronic tech check this out.

If you have had swing away footrests on this chair you can replace them with model PHW93 and must ask to get them in red when you order them from a wheelchair store. If you dont know where a store is that sells Invacare products, call Invacare customer service at 800-333-6900.

Judy He has to disconnect the joystick cable and then pull the seat off the post raising up the seat turning lever and twisting and pulling upward on the seat at the same time. It can be hard because the seats are heavy and can be rusted. Just keep pulling and turning at the same time Once he has the seat off he can remove the cover over the batteries and disconect the cables going to the batteries and the large connector going to the power pack. Reinstall the new batteries just like the old ones replace the cover. Put some axle grease or vaseline on the seat post reinstall the seat plug in the joystick cable and you should be good to go Hope this helps

Sorry the joystick doesn't like rain or coffee or wet conditions and you will have to have it replaced. Next time carry a wally world bag with you and put it over the joystick to keep the moisture out. you can still steer and use the buttons through the bag Hope this helps

OK hope I can help

You can't You will have to replace the left motor/gearbox/brake assembly. The controller checks that you have a good signal from the brake and will not move if it doesn't get one disengaging the brake will not remove the fault and the chair will not move. If Medicare paid for your chair than they wil pay for repair. Contact the provider that sold you the chair and ask if they can repair it or contact Repair Express @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668 to see if they can have a tech come out to repair your chair. Hope this helps you
