My quantum 6000 yellow light on joystick monitor reads left motor disconnected

<div><br>The first two red diodes flashing accompanied by beeping on your Quantum 610 electric wheelchair generally indicates a fault condition or an error code. Here are some possible reasons: Joystick Calibration Error: The joystick may need to be recalibrated. Check your wheelchair's user manual for instructions on how to calibrate the joystick properly. Error Code Identification: The flashing lights and beeping may be an error code. Consult your wheelchair's user manual to interpret the specific error code, as different combinations of lights and beeps can indicate different issues. Battery Issues: Low battery voltage or a battery fault can sometimes trigger error codes. Ensure that the wheelchair's batteries are fully charged and in good condition. Motor or Drive System Issues: Problems with the wheelchair's motors or drive system may prevent it from moving. Check for any loose or disconnected wires in the motor connections. Obstructions: Ensure that there are no obstructions or obstacles preventing the wheelchair from moving. Check the wheels and drive system for any debris. Controller or Joystick Malfunction: A malfunctioning controller or joystick can cause issues. If possible, try using a backup controller or joystick to see if the problem persists. Reset the System: Turn off the wheelchair, wait for a few seconds, and then turn it back on. This may help reset the control system. Technical Support: Contact the manufacturer's technical support or customer service for assistance. They may be able to guide you through additional troubleshooting steps or advise on the next course of action. Professional Inspection: If the issue persists and you are unable to resolve it through basic troubleshooting, consider seeking assistance from a certified technician who specializes in mobility devices. Always refer to your wheelchair's user manual for specific information on error codes and troubleshooting. If you don't have the manual, you can often find it on the manufacturer's website or by contacting their customer support. <br></div>

You may be looking at a sudden/intermittent electrical short OR one of your connectors may be loose?

Your chair voltage REGULATOR may also be going bad which appears to be WITHIN the "Main Brain" of your chair?
"TECO FM-50"

From the above schematic ~ there is a "Potentiometer" shown (lower left) that MAY be 'dirty' and needs a tiny squirt of "QUALITY" contact cleaner WITH SILICONE to help keep the internals clean... looks something like this (a Google Search):




I would also spray ALL of your control switches too including the inside of your joystick controls! Just a REAL QUICK squirt should do it... if it drips, you've used too much.

I hope this HELPS YOU!

after do a test restart the chair. make sure both freewheel levers are locked in drive mode (hard to push), restart, make sure your connections are good, to the motors and brakes. what kind of Joystick is this?

The age of the Nutron is not the issue, unfortunately. I have seen problems with this model right out of the box. The joystick control is the first area to check. If you have to compensate the joystick so far to the right to correct, you may have a damaged joystick gimbal. You may also have a bad joystick control board or damaged connecting cable to the controller on the bottom frame. Check for damaged, pinched loose or disconnected wiring below at the controller module. With a folding frame it is easy for the wiring to be become damaged or dislodged. Check for cut damaged pinched wiring at the joystick. With a handheld programmer (dealer) you can check for error codes in the fault log. With a poor performance issue there may not be a fault recorded in the log of the computer module. I have also seen these motors fail prematurely. In this case your left motor is dragging or weak causing the chair to go left. With a programmer (dealer tool) you can compensate for this while waiting for new parts(temp fix). Sometimes the motor brushes burn or hang up. Try blocking up the chair off the ground and run it no load to check for motor performance and unusual sounds. Check for joystick dead spots or uneven action. A quick check of the joystick would be to plug in a known good one at the dealer to test. With the chair blocked up try tapping the motor housing to see if the performance changes. Inspect the brushes if you have access to the brush caps.Check the obvious first, plugs, pinched, broken wires and partial plug disconnects and corrosion. If you have a voltmeter you can do some checks on the motors and brakes. Going from memory, the motor leads large black and large red should read zero ohms with the 2 small white wires for the brake reading between 60 and 70 ohms. Check the Invacare manufacturer website for exact specs and technical info for this model.
Hope this helps.

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.

One of the most common controllers, codes to help you and others.





VSI & VR2 Joystick error flash codes:
1 RED BAR:Low Battery Voltage The battery is flat (more likely).
Or the battery has a bad connection (which is unlikely)
2 RED BARS: Left Motor Disconnected The left motor is disconnected. Check all the connections for physical disconnection or corrosion or burning usually caused by the salt poured onto the roads every winter.
3 RED BARS: Left Motor Wiring Trip The left motors wiring has a short circuit. Check all connections and leads for wear and chafing between the left motor and the battery cables or chassis
4 BARS: Right Motor Disconnected The right motor is disconnected. Check all the connections for physical disconnection or corrosion or burning usually caused by the salt poured onto the roads every winter.
5 BARS: Right Motor Wiring Trip The right motors wiring has a short circuit. Check all connections and leads for wear and chafing between the right motor and the battery cables or chassis
6 BARS: Activated if you turn on your wheelchair with an external device like the Charger still connected.
7 BARS: Possible Joystick Trip, Make sure that the joystick is in the centre position before switching on. If you still get this when switching on then joystick is probably faulty.
8 BARS: A control system trip. Make sure that all connections are secure and if so the power module or control pod is probably faulty. Test by substitution of known good one.
9 BARS: The parking brakes have a bad connection or have a failed solenoid, or any lever or switches that disconnect drive for pushing the chair manually may be pulled or switched.
10 BARS: Over voltage detected. This can happen with a bad battery connection although unlikely. More likely your battery charger is faulty and is overcharging your batteries quite severely.
1 BAR to 10 BARS and back in a "ripple" every few seconds. Joystick not cantered when turned on. Switch off and try again.
1 BAR to 6 FLASH every few seconds. System Asleep. Switch off and back on. Time before sleep can be adjusted or disabled in programming

Hi
delobner,

Sometime we lock our vsi joystick by mistake. Here are the instructions on how to lock and unlock your joystick.

If the problem is still there after write me back and I'll help you.

LOCKING/UNLOCKING THE VSI

The VSI has a feature that enables you to lock your power chair to prevent

unauthorized use.

To lock the VSI:

1. With the VSI powered on, press and hold the on/off key. After one (1)

second, the VSI should beep.

2. Release the on/off key.

3. Push the joystick to the full forward position until the VSI beeps.

4. Pull the joystick to the full rearward position until the VSI beeps.

5. Release the joystick. There should be a long beep.

6. The VSI is now locked.

To unlock the VSI:

1. Press the on/off key and power on the VSI. The maximum speed/profile
indicator should ripple side to side.

Good Luck

According to my 1170 manual the flashing lights are error codes. 1 red = low batt., 2 red = left motor disconnected, 3 red = Left motor wiring fault, 4 yellow = Right motor disconnected, 5 yellow = right motor wiring fault, 6 yellow = Inhibit active, 7 yellow =possible joystick fault, 8 green = possible controller fault, 9 green = Solenoid brake fault, 10 green = high batt. voltage

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.

THE WHEELCHAIR WILL ONLY TILT IT WILL NOT GO FORWARD OR BACKWARD USING THE JOYSTICK
