When i turn on my chair it reads controller and does nothing but flash controller


If this is when the charger is plugged into the chair, the chair goes into inhibited mode so you cant drive away towing the charger with you. A safety feature.

No lights on joystick


Here is a parts catalog for the M41. http://www.invacare.com/doc_files/06_108.pdf

If it was working fine before you swapped the batteries then you did something to interrupt the current flow. Pages 49/50 show the location of the controller with a picture. Unplug the connections here and make sure they are clean and in good shape. Make sure all other connections are clean and tight.

If you have 24V coming off the batteries into the controller, and 24V going out to the joystick from the controller and still nothing is working, then you will probably need to get ahold of an Invacare service tech to replace the joystick. Before he does that he should swap out the old joystick with a new one to see if that is the issue. Invacare parts are pretty pricey...joystick by itself is over $500.00. If the controller is shot, then you can double that cost. Sometimes, both need to be replaced as they can kill each other.

If the chair is old or has a lot of hard hours on it, you can usually shop around on Craigs List, etc and find a good newer/near new chair for about the same price as a new joystick replacement.

My Invacare TDX SP has died on me and someone told me of a trip switch on the batteries..Anyone know where this switch is as all I can see are bolts and metal?


http://www.invacare.com/doc_files/1143190.pdf
Owners manual for TDX SP link above.

First check if you have power present at the charging port. If you have power (24 volts) then the batteries and wiring are not the issue. If you don't then check the battery post fuses. These are "L" shaped brackets with a white square fuse held on the positive post with a through bolt and nut. On older chairs these are known to become loose and or blow just when you need power or stop suddenly.
Also check the big Anderson connectors at the power point at the end of the battery box. Check for solid connections. If there is 24 volts here to the control box, next check the controller connector.
If there is +24 at the controller connector but 0 at the joystick charger port you have big issues. Either the traces connectors in the controller are fried or your joystick has major issues.

No display, won't charge, dead, after cold storage


hi, you say the voltage is 3 volts each, then it never work , remember it's requires at least 18 to 20 volts to light up.


if a battery measure's below 10v it's normally impossible to charge again as a lot of chargers will not go below this level, you could try a car battery charger to bring the level up however do this with care and don't leave on charge

I have a Pronto M91. When I push the joy stick the lights turn off and the first two red lights blink. I check all the connections and the wheelchair will not move. I would be thankful for any help.


You have low batteries and need charging if you been charging and still get the red lights then the batteries need to be replaced and have the charger checked for correct output. If you have a voltmeter you can check the charger by plugging the on-board charger into the wall set the voltmeter to 200 volts dc and plug the leads into the two outter holes of the charger port located under the front of the joystick. with the charger pugged in you should be reading 27+volts if you aren't getting any reading or the reading is lower than 25 volts then replace the charger or get an offboard charger and try charging the batteries via the joystick charger port Hope this helps

Power failure


The batteries may not be dead. When pulling a hill especialy for long periods, you may draw too much current and the circuit breaker will open. If you wait a few minutes you can reset it and resume. If the batteries are not fully charged or in good condition, the unit will shut down it total system voltage drops below 17 volts.

Scooter stops short without warning


This could be caused by a couple of different issues. If your batteries fall to below 17 volts the unit will shut down. After it sets for a few minutes it may run again for a short time. If this is the case, then the batteries are not being charged properly or they are not holding charge.
Another cause could be the break switch circuit is opening. If that is the case, replace the brake/motor harness
