Elctric wheelchair, flashing rapidly the error display

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.

more info needed, what chair and what controller? is it all lights or just some and if so how many? are there two sets of lights (one for battery one for speed)? with out this info can not help.

I will have a guess and provide the error info for the most common possibility 10 lights flashing "An excessive voltage has been applied to the controller. This is usual
caused by a poor battery connection. Check the battery connections."


If this helps please click the "YES" button to let others know it is helpful.

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...

3 flashes indicate that there is a short circuit to the left motor and battery connection. Check wiring and connections

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.

NEW BATERIES NEEDED

To diagnose the problem, I need to know how many bars are flashing. If the power chair was jsut working and now it is not, you may have accidentally knocked a manual brake lever out of position with your heel. Take a look at this website to find out what the flashing lights may indicate is wrong with your power chair.

Rapid discharge usually is a sign of weak batteries, and they should be replaced if the charge indicates that they are full after charging for several hours, and then dissipate rapidly.

If your not getting a full charge indication after several hours, then you need to check the charger to make sure it is putting out about 28 Volts DC. If it is, then it is for sure the batt's.

The sweeping lights should not occur when the chair is off the charger. They sweep while on charge to tell you that it is charging and you can't move the chair. If they sweep while off the charger, turn off and restart and it should go. If not, call a tech. rep. for Quickie.

Hi

Rapid flash of lights indicates a fault in the VSI or the electrical system. You need to refer to " VSI Error Codes" on page#32 of this User Manual:

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

Try using a Voltage meter to test the Voltage coming from your batteries. Your batteries should be as close to 12v. your motors are 24v. Even if just one battery is bad this can cause alot of headaches.
