SOURCE: 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.

SOURCE: Can't charge Pronto M91.

Hi Bob. Unfortunately in most cases this means that the batteries have gone so flat that they cannot be “revived”. The best thing to do is take the batteries to a local battery dealer and have them checked. You may need to replace them. Another possibility is that because the batteries are so flat, the charging circuit hit a wobbly trying to resuscitate them and popped a fuse button. A simple reset may help. Happy scooting. Regards Chris… info@mymobility.co.nz

SOURCE: CAN'T LIFT OFF SEAT OF JET3 POWER CHAIR? batteries

Richard The seat is probably rusted on the seat post It will take alot of turning and pulling upward at the same time to get it off. Try spraying a penetrant on the post just below the seat to see if that will help with the turning and pulling just keep at it. It can be a tedious task and frustrating Hope this helps

How do I get my pronto m91 out of charging mode?


The M91 has an onboard charger. When unplugging the charger power cord from the wall outlet does not stop the chair from being in the charge mode, The charger has to be unplugged from the wheelchair wiring harness or main control module under the plastic body parts. The on-board chargers fail like this sometimes.

Is there fuses in the M91 Pronto Onboard charger


I had this exact same problem after having my M91 in the shop. The repair man said that the onboard charger was bad, so he sold me an offboard charger to charge through the arm. That didn't change anything. I finally took it apart myself and discovered that there was a cord leading from the onboard charger to the batteries that the repair person had left unplugged when he installed my new batteries.
What I'd thought was "fast draining" of the batteries was actually the batteries self-charging overnight (which they will do a little bit if you let them sit). Of course, this might not be your problem, but I'd say at least look at it as a possibility.

I need to know what kind of baskets that can be used on m91 wheel chairs. thank you .


Mid-wheel drive Power Chairs can only use baskets that attach to the rear of the seat. I know this isn't much help to the user in the seat to reach around to use and also leaves any items placed in the basket open game for someone walking by with sticky fingers. Other than a flat tray for the front, there isn't anything else available.
The best basket will have a square post attached at the bottom and it will slide into the matching receiver bracket located under the seat. If your chair does not have the receiver under the seat, then you will also have to purchase that add-on accessory as well as the basket. Look in the phone book in your town to see if there is a medical store that sells mobility accessories. You should be somewhere in the $70 to $80 range for the price.

I have worked on power mobility for 20 years and have often though about inventing a front basket for the Pronto and other mid-wheel drive chairs. The problem is with the expense of the red tape just to do patent searches and then there is libiality issues to deal with as well.

Can you bypass the tilt recline mercury switch on pronto m 91


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 Pronto will not keep a charge so I replaced the batteries. Now the red and green light flash while charging and there is no power to the chair


Mckinzie the lights will flash when charging because of the inhibit mode. After you unplug the charger and turn the chair on do you get any lights at all on the battery indicators? If not lift up the seat and check your battery cable connections the neg cable from the rear battery should be connectd to the positve side of the front battery and the rear neg should plug into the small connector of the other cable. Make sure then that the large double plug is connected to the double plug going to the controller. while the seat is up then turn the chair on to see if all the lights come on. If not check that all your connections at the battery posts are tight. Also check under the two red positve battery post covers the two fuse links to make sure they are not blown. If all of this checks out the chair should come on and operate correctly Hope this helps
