My prontom51 willnot move trouble light
The Invacare Pronto M51 with a flash code of 6 indicates a right brake fault. This can mean several things and there are several solutions to this problem.
The brake lever can be in the wrong position and the brake can be in the release position. Work the brake lever up and down and see if this clears the fault and the chair drives.
There could be a bad connection from the motor to the controller in the base. Check the wiring for cuts and breaks. If you can get to the wiring plugs from the motor (there are two) check the connections and plugs for corrosion and a good connection.
To verify that you have a bad brake you need a digital voltmeter to check the resistance of the electromagnetic brake coil. It should be about 40 to 60 ohms across the two white connectors. You can check the motor at the same plug. If you have made these checks and the motor and brake test good then you have a bad controller output to that motor. This can be tested by swapping the motor outputs from the controller and see if the error code goes to the left motor output. The controllers run about $1000 retail and a technician can verify this a second time by taking a good known controller and plugging it in to see if the chair now runs.
In my experience if the motor/brake/gearbox assembly is more than 3 years old have it replaced. That being said, an experienced technician should verify a bad brake/motor/gearbox assembly first. On this chair, the only cost effective repair is to replace the entire brake/motor/gearbox assembly. The retail price is about $700. Keep in mind that if the right assembly is worn out the left is not far behind. Typically if insurance will pay for the repair, I opt to replace the left and right brake/motor/gearbox assemblies at the same time so you do not pay for the labor and inconvenience twice.
Try the simple fixes mentioned first, and then have a technician evaluate the chair for the other problems I have discussed. Hope this helps.

Have a Pronto m91 power chair. Suddenly stopped
Sounds like you are on the right track with your problem solving. Unfortunately you cannot determine an electronic fault by visual inspection of the components. You can see cuts, nicks, broken wires and burnt components, but this only works sometimes.
I look at the current fault code with a hand held programmer (HHP). With a HHP you can read the fault log and check out all the stored codes to get an overall idea of the history of chair problems. The 7 flash code is definitely a remote fault. You can also get this fault with a bad connecting cable between the joystick (remote) and the controller (in the base). Check this connecting cable for breaks, cuts, loose pins or connections and check the connections at both ends. You can do continuity and component checks of the remote with a digital voltmeter, but this is out of the realm of most end users.
I am assuming you have MK5 or MK6 electronics in this discussion.
The easiest test is to swap out the joystick with a known good one that either a tech has brought to your home or you have brought the joystick in to a service center for testing. The better test is with a HHP that will give you the current problem and stored information of past problems.
Weak batteries or loose battery connections can also give a myriad of electronic faults. For this reason I always check the batteries and battery connections first.
The joystick can be rebuilt, but I recommend replacement as a more cost effective solution. I always replace the joystick to controller cable too. Labor charge for this work is under 1 hour.
I can provide further information if needed. Hope this helps.

Can you bypass the tilt recline mercury switch on
The mercury switch for the TRSS (tilt recline single switch) is a mercury switch with a molex connector on the end. The switch opens and closes depending on the angle of the chair with mercury or a ball closing the contact.
Yes, you can bypass this switch, I do it all the time when it fails. Follow the wire from the black torpedo shaped switch. Unplug the switch at the white molex plug eliminating it from the circuit. Inspect where it was plugged into and observe the female contacts in the molex connector. Take a paper clip and bend it to shape inserting it in the two female contacts, shorting across them. This, in effect, acts like a closed switch. Tape up this connection with tape to hold the paper clip in the connector. Use the same tape to secure the connection to the chair.
When you replace the mercury switch the new ones that are available are the new ball switch type. The mercury has been removed due to environmental concerns. The angle of this switch when installed should provide drive lock out at the factory specification of 20 degrees tilt. Mark the position of the old switch and wiring before removal. It is usually easier to get to this switch by removing the chair seat pan first. Adjust the angle of the new switch (about $70) on installation. You may have to cycle the tilt up and down several times to accomplish this, testing for drive lockout at 20 degrees.
You can safely drive the chair until a new part is obtained but remember you are defeating the safety feature of the drive lock out in tilt by bypassing the switch. When you are tilted back too far you can tip over so exercise caution when going up ramps and inclines. Hope this helps.

The wheels on my friends
Jet turn the speed down on the chair to try a slower speed it might help with the spinning and make sure the casters are turning freely and not creating a bind or excessive drag on the drive wheels. Good Luck Hope this helps you

Twice now, within 6 months,
Ok the heating up part means that there is something wrong with the power ciruit itself, chances are something is outputting more power than it should, disconnect the joystick box and see if the motors heat up, I'm betting it wont. The reason being that the joystick box has several switches in it, 1 or more of them is feeding power back to the ground which then transfers it to the motor causing cavitation in the motor circuit it self, e.g. Forward and backward at the same time, but since u push foward that gets more power so it moves or vice versa., Once you verify the above I dont think you need to replace the entire box, but clean the contacts or change the switches, only then change the box if the problem persist.
Now 1 symptom of the above is a reduction in power (the chair now isnt as fast as it should be)
Fixing the above will fix all on that. Please let me know after you have the shop check these things out.

Rear wheels making a poping
Sounds like the rear axles are a little loose. More likely the rear wheel bearings that fit in the hub race of the wheel are worn out. There are 2 bearings per wheel or 4 total for the 2 rear wheels. They are available from The Aftermarket Group. com. To install, remove the wheel axles and pop out the bearings. Use a soft mallet to hammer in the new bearings. Do not overtighten the axles on assembly. The wheels should spin freely when the wheel is in the air. Hope this helps

All lights blink together at
claxtonbrent That is the error code for a bad right brake and it will have to be replaced. There is no quick fix for this problem. It requires a new brake and I'm not sure if you can replace just the brake Usually when I get this and Medicare is paying for the repair I have to order a right motor/gearbox assembly. you can contact Invacare @ 1-800-333-6900 ask for M51 tech support and ask if you can replace just the brake Hope this helps

My m91 apears to be charging, then goes to solid
Randal the problem sounds like a battery issue. If after charging you get a green light on the charger and the batteries run down quickly there is one or both of the batteries that is weak and cannot handle the load required by the motors. If Medicare paid for your chair contact the provider that sold you your chair and ask them to come replace the batteries. They should then bill Medicare for the batteries. Hope this helps

Sometimes, out of the blue,
With the M91 the click you are hearing is the electric brake solenoid engaging and disengaging the electro mechanical brake. The display blinking probably indicates a brake solenoid fault code and right or left motor. Try working both brake levers back and forth listening for and feeling for smooth action. If the levers are bent and the brakes are not working a motor replacement is necessary. If you can identify the fault flash code you can determine which brake or motor is the culprit and use a DVM to verify the component failure.

Batteries not charging
This is a manual wheel chair, there are no batteries. If this is not wheel chair you are asking about, the batteries may need to be replaced. They can become damaged if they have been stored or sitting unused for a while.

Turned on switch, everything lights
Usually when the control stick refuses to perform any function it is as a result of a disconnection somewhere below. If the power comes on and all other things function properly then the control stick malfunction is as a result of a disconnection. Send the unit in for servicing and proper diagnosis.
Hope this solution has been helpful?

I have a Pronto M6
Make sure all of your connections are tights and the your fuses do not need to be replaced.
Blinking lights on the controller usually indicates a problem, the number of blinking lights are used to diagnose the problem. Take a look at this website to identify the type of controller you have on your scooter so you can dtermine what the blinking lights are trying to indicate.

After receiving this particular chair I had
imwaltz Sorry buddy but if it sat that long the batteries are probably too low for the charger to pick up and charge. to bad you didn't just charge those batteries once a month while you were laid up. You will have to get new batteries. If Medicare paid for your chair they will pay for most of the repair costs. Contact Repair Xpress @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668 these are 2 excellent service companies that will bill Medicare for repair and have a tech repair the chair for you. Hope this helps

The battery will not hold a charge for very long
Bronnaf Well probably. How old are the batteries? If they are 2 years old or older yes I would say they are bad. If you have not any problems before and then I'll assume the charger has been working and still getting a full charge but the lights fall off quicker than before Yes you need new batteries. Now Did Medicare pay for your chair? If they did then they will pay most of the repair costs. You can contact a repair service and they will fix your chair then bill Medicare You would have to pay any deductible that Medicare doesn't pay. Contact Repair Xpress @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668ou
