Merit DL 5.2 i, electric wheel chair, all leds flash 3 times. I beleave this is a error code. what does it mean?

If your Dynamic DL 4.2i electric wheelchair is experiencing issues where the LEDs are flashing and the chair won't move despite fully charged batteries, there could be several potential reasons for the problem. Here are some troubleshooting steps you can take:

1. Check for Error Codes:
   • Electric wheelchairs often have a diagnostic system that uses flashing LEDs to indicate specific error codes. Refer to the user manual for your wheelchair to interpret these codes. They can provide valuable information about the nature of the issue.
2. Inspect Connections:
   • Ensure that all the electrical connections, including those between the controller, motors, and batteries, are secure and free from corrosion. Loose or damaged connections can disrupt the functioning of the wheelchair.
3. Reset the Controller:
   • Some wheelchairs have a reset button on the controller. Try resetting the controller by turning off the power, waiting for a few seconds, and then turning it back on.
4. Check Joystick Operation:
   • Verify that the joystick is functioning correctly. Sometimes, issues with the joystick or its wiring can affect the chair's performance.
5. Test Batteries:
   • Even though you mentioned that the batteries are fully charged, it's worth checking their voltage and overall health. Faulty batteries can still show a full charge but may not provide sufficient power.
6. Controller or Motor Issues:
   • If the problem persists, there could be an issue with the controller or the wheelchair's motors. In such cases, it's recommended to contact the manufacturer's customer support or a qualified technician for further diagnosis and assistance.
7. Professional Inspection:
   • If the wheelchair is still under warranty, consider contacting the manufacturer's customer support for assistance. If not, seeking the help of a professional technician with experience in electric wheelchair repairs may be necessary.

Always prioritize safety when troubleshooting or attempting to fix issues with electric wheelchairs. If you are unsure or uncomfortable performing the troubleshooting steps yourself, it's best to seek professional assistance to ensure the wheelchair is properly diagnosed and repaired.

Most of the time a flash code of 8 means the controller has a fault. but sometimes there maybe a damaged cable connecting the joystick to the controller.Sorry for the bad news.

What if the speed LEDs on the VR2/VSI begin to flash?

• Determine if the battery charger is connected to the power base. When the battery charger is connected to the power base, a charger inhibit feature keeps the power chair from driving. This is indicated by the VR2/VSI speed
  LED(s) flashing.
• Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to
  activate.
• Determine if all controller connections are plugged into the power base properly. If the 3-pin charger
  inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

Make sure the manual brake isn't down.

If your M41 has the mark V controller that is seen pictured in the stock photo you provided, the 5 flash code is a left park brake fault.
1. Turn off the chair.
2.Disengage the left motor (levers are located in front under the seat) roll the chair back and forth and re-engage the left motor.
3. Engage the left motor.
4. Turn on chair.

If you happen to have the older Mark IV controller (has a toggle switch to turn on/off and three battery lights), the 5 flash code means the chair is receiving high or low voltage from the batteries. I would recommend having the batteries checked.

If the chair stops flashing, you are good to go. If the chair is still flashing, you will need to contact a technician to possibly replace the left brake. I recommend Repair Xpress FixMyPWC com Nationwide service and delivery solution for power...

Code 8: Controller problem. Also, check to see if your gearbox levers are engaged - if you can roll the chair by hand the gearbox is not engaging the motors.

This problem may depend on which main controller your chair has fitted. It should be a Penny & Giles GC controller. US versions should have a GC3 whilst here in the UK, it would be fitted with a GC2. However, the diagnostic flash codes for these two controllers should be the same. The reason im slightly confused is that you say 5 flashes mean your charger is connected at power up, when in fact it should be a Right Motor Wiring Fault. 9 flashes is indeed a Solenoid Brake Fault, or in other words, the wheelchair is in 'Free Wheel' as you have described. Therefore, IF your controller is in fact a Penny & Giles GC, 7 flashes would mean a Joystick fault. There is not much you can do to diagnose this other than checking connections between the Joystick and main controller. If these are OK, it is likely that a new Joystick controller will be required as having these fixed is usually not cost affective. Hope this is of some help to you.

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.

The service light indicates a problem. Count the number of flashes. ie flashes 4 times pauses flashes 4 times etc. If you have the owners manual the flash code section will tell you what the number of flashes mean: 3 flashes left motor 4 flashes right motor. You will have to contact a service company to repair the chair once you find out what flash code you have. If Medicare pirchaed the chair then they will pay for most of the repair cost. Hope this helps

The number of lights that are blinking indicate what the problem is. Visit this site to locate the type on controller on your power chair and you will be able to see that the blinking lights mean:

Try to reset your manual brake release as this is a common problem.
If you continue to have a problem, contact your manufacturer or dealer for service. If your insurance purchased they power chair for you, they may also cover the cost of repairs.
Good luck!
