It very well could be that the motor is burned out. That motor would need to be taken out of the chair and bench tested to make sure. The other option could be the wiring going from the controller to the motor. If that wiring has a problem, it would not feed power to the motor.

Nutron r51


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.

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.

Invacare MKIV R11 Flashing lights


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

powerc24.jpgpowerc25.jpg



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


Hope this helps, If so please click the "Yes" button

Our Jazzy Select G.T. power wheel chair won't run. The lights keep blinking when the power is turned on but won't run..? Why? Battery is charged.


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

My Drive Cirrus Plus power wheelchair doesnt move, it flashes the first two LEDs in red and when moving the joystick it won't move or make the sound. What could be wrong? The battery is at full charge


The Drive Cirrus Plus power wheelchair is a folding frame chair with a VSI controller. The VSI controller (joystick) will indicate a fault code when it detects a problem with your power chair. It is manufactured by a company called Penny Giles Drive Technology. An LED flash code of 2 on the battery display indicates that the left motor is disconnected. There may be a brake fault also.

The left motor can be disconnected at the plug where the VSI harness plugs into the motor plug. The pins for the motor or VSI output may be pushed back in the connector or not making contact due to corrosion or dirt. Unplug this connector and inspect the pins and make sure they are making good contact and are clean. Spray contact cleaner on the contacts to clean or re-orient the pins to make better contact. The folding frame of the chair may have dislodged the connector. The wiring harness from the motor may be pinched or cut. The brake wires and pins may have become disconnected also. The brake lever may be in the disengaged freewheel position causing a fault, so put the brake lever in the correct position. Strictly speaking, this fault code is for the motor only, but always check the motor/ brake assembly since the wiring runs from the same plug.

A certified technician will have a hand held programmer to read the computer (VSI) fault log and determine the number of error codes for the various components.

Using a digital voltmeter you can check the motor at the plug. The two large wires on this 4 pin plug go to the motor; the two small wires go to the brake. On the resistance scale the motor should read between 0 and 1.6 ohms. The brake should read between 30 to 60 ohms.

There is a chance that the output of the VSI controller is bad. To test this swap the left and right motor output connectors from the VSI. If the error code now indicates right motor disconnected (flash code 4) you have a good VSI and bad left motor. Swap the leads back after you are done with this test.

Try blocking up the chair and see if the motor runs with no load on it or after spinning the drive wheel by hand. You can also inspect the motor brushes for burning and wear. If you pull the brushes, do this carefully and blow out the dust from the motor armature. This may allow the motor to work again for a short time.

You will probably need to hire a technician if, after checking for bad connections and the brake lever in the wrong position, you still have problems. I like to replace the brake/ motor/ gearbox as a complete assembly to avoid future problems. Labor for the diagnosis and reading the fault code log with a hand held programmer should be under 1 hour. A return visit to replace the motor brake gearbox is under 1 hour. Hope this helps.

What can be used to clean the contacts on the Shark power module for our CTM HS 2800 power wheelchair? There are 2 red, 2 yellow & 2 green lights on this chair that flash once and go off and then come...


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.

I have a invacare wheelchair pronto91 wont move 2 red lights flash 3 times


The three light flash indicates a short circuit between the left motor(as you are sitting in the chair)and the battery. Check all the wiring from the control box to the motor and make sure it is not damaged in any way. If it is okay, you have most likely fried the left side motor. A new motor-gearbox assembly for this chair runs in the neighborhood of $1,400.00, or you can take the motor off and take it in for a full rebuild for about $250 or so. Unplug the joystick and remove the seat and cowl. Jack up the left side with both motors in gear. Remove the center nut cover and take off the nut holding on the wheel taking care to retain the key that slides into the groove on the axle. Disconnect the wiring plug to the motor and remove the six bolts holding the motor to the frame. Separate the gearbox from the motor and take the motor to a rewind shop for repairs. Reinstall and it should be good to go.

Motor Wiring


Two white wires are for the electric brake.  When the wheelchair is turned off while on an incline, the motors automatically lock up, preventing the wheelchair from rolling backwards.  The white wires disengage the electric brake when power is applied.
