SOURCE: What can be used to clean the contacts on the

This power wheelchair uses a Shark joystick control made by Dynamic. The connecting cable plugs into the back of the joystick control and can be unplugged by pulling back on the lock ring of the connector. Spray electrical contact cleaner onto both the plug and the joystick cable receptacle.
Follow the cable down to the base and check for cuts, nick or pinches and repeat at the base connector. To get to the power module you need to remove the seat and cover for the base. The controller should have 5 connectors plugged into it. One is the power connector, one is the right motor, one is the left motor, one for the joystick plug, one for the charger. Remove these connectors one at a time, spray clean the contacts and plug back in. Inspect these connections on both sides and be certain the contacts are shiny.
A 6 bar flash indicates that there is a right park brake fault. Work the right brake release lever up and down several times and see if this clears the fault. Do the same for the left brake. If you have cleaned the right motor plug at the controller by disconnecting it you can use a digital voltmeter to test the brake. The 2 small wires to the plug are the brake wires and should read 40 to 60 ohms on your meter. If the brake solenoid reads open or shorted your brake is burnt out. The two easiest things to try are moving the brake levers and spray clean all the contacts. The test/replacement of these parts requires a qualified technician. Hope this helps.

What does 3 blinking wrench lights mean?

It is indicating a left motor fault, which is not good news. This is usually from a motor overheating and burning out, usually from overloading the chair or from driving it on unstable terrain like mud, snow, wet grass or sand. If that is the case, there could be more damage to the electronics once you get the motor replaced too. Replacing the motor is a lot of work and very expensive, so you may want to try to find a replacement chair.

What does a yellow wrench indicator light mean on a Pronto M41 w/Sure Step?

The yellow wrench is a diagnostic tool. How many times does it blink between pauses. Example might be 3 blinks then pause then 3 blinks then pause, over and over. Hoe many does your chair blink?

Yellow invacare wrench

Motors must be fully locked in gear to drive. Also many chairs require the joystick to be turned off before putting them in gear or turn chair off and back on after engaging the motors.

Lock key keeps blinkinglights blink 9 times

Depending on the controller type being used you either have a controller solenoid brake fault (sticker on bottom of joystick will say "PG Drives" and have 9-bars flashing) or a communication error between the controller and joystick (Dynamic Controller flashing wrench).
Repair for PG Drive is to replace joystick/controller.
Repair for Dynamic is to clean, remove and reseat or replace joystick cable.

Switch not working

I have an older electric Perfect Chair model and the switch has go out twice.
To fix mine here's what I did. you will need a butterknife, scotch tape, flat screwdriver, allen head wrench to fit screws on inside panel.
1. Scotch or painter tape on the wood around the switch so as not to scratch it.
2. Pop the switch box out of the wooden chair leg by using a butterknife edge (similiar flat tool will work).
3. There are six wires attached to the switch-single orange, double orange, single yellow, double yellow, blue one and a red one. Diagram which
wires go where so can hook back up correctly.
4. Unhook the wires from the switch.
5. Easier to rehook up the wires if remove the panel from the inside of the wooden chair leg. Need the correct size allen head or six sided wrench to remove the the 3 screws on this panel.
6. Open the switch by popping up the button. gently use a small screwdriver to do this.
7. There are 2 small metal slips/pedals at the bottom of the switch. the switch stops working when one or both of these get out of place.
8. Need to replace the metal pedal in correct position.
9.Replace the the button on the switch carefully to avoid disturbing the metal pedals.
10. Hook up the switch wires-see #3 and 5 above. my chair worked after this fix ! let me know if this helps -

Blinking yellow wrench light on pride jazzy 614 HD

Your version has a Dynamic Controls model controller and joystick.
Unplug the charger and engage the motor/brake lever so the chair is no longer in free-wheel mode (con't push by hand)
Turn the chair off, wait 5 seconds, turn the chair back.
If chair still does not run and your wrench is flashing you have a problem. Count the wrench flashes - the flash count indicates the error detected. 3, 4, 5, and 6 flashes indicate and error with the motors.
3=Left motor fault
4=Right motor fault
5=Left brake fault (may not be engaged)
6=Right brake fault (may not be engaged)
Any other fault code usually means the electronics or wiring is bad and not worth fixing.

Blinking yellow light plus thespeed button is broken and i cannot increase the speed enough to move fast enough to be able to safely move in traffic

Horne the blinking yellow light is an error code and tells you have a problem with the chair. The speed button will have to be replaced by ordering a new faceplate for the joystick. You shouldn't be driving the chair in traffic but if you have to be very careful you could get a ticket or worse yet run over. I would contact a repair service to fix your chair if Medicare paid for it they will pay for 80% of the repair. Contact Repair Express @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668 if you would like to get it repaired Hope this helps

Battery indicator seems fine. Wrench symbol is lit. Chair won't respond to joystick control. Any suggestions? It worked when I put it away a few months ago and now, nothing.

The wrench symbol being lit indicates a problem. Does the wrench symbol blink? when you try to engage the joystick the brakes should try to engage and you would hear them click and the symbol will flash. The number of flashes telling you what is wrong. If the symbol is not flashing and staying on then that also a probem but you can't tell what it is. Either way the chair will have to be checked by a tech that has a programmer to plug into the chair and read the error codes to determine the problem. Check with your provider that sold you the chair to see if they can troubleshoot the chair for you or contact Invacare Tech Support @ 1-800-333-6900 and explain your problem. Sorry I can't give you a definite answer Hope this helps

My pronto m91 was flashing 5 times on the yellow led and after i resert it like you said it ran for a minuet and now it flashes 4 times on the bottom yellow led.

I am new to this request. Hope you have had your chair fixed by now, but in case not. If you still need help I really need more chair information. What joystick? Many different joysticks with different yellow lights. With a 4 or 5 blink it could be a motor or battery voltage problem.
