As a fellow, tormented wheelchair user, I’ve hassled every expert in the field and finally figured out what those lights mean: Your chair is telling you, “Hey you, help me now – Or else…”

In fact, thanks to my extensive research and hands-on experience, I’m here to guide you through understanding and resolving this common yet perplexing issue – and it’s dead easy!

Read on to discover what I learned about the lights flashing problem ASAP…

Key Takeaways

  • Decode the Lights: Learn the blinking light codes: each pattern has a unique meaning.
  • Consult the Manual: Always check your user manual to decode and resolve those light codes.
  • Seek Professional Help: If you struggle or are in doubt, contact a technician for a thorough diagnosis and repair.

Jazzy Power Chair Blinking Lights | 6 Causes You Can’t Ignore

Those blinking lights on a Jazzy Power Chair signal various issues: a drained battery, motor wiring faults, overvoltage, worn-out batteries, brake issues, or poor connections. Each blinking pattern is a direct message indicating a specific problem, requiring immediate attention and action.

Here’s a breakdown of these 6 causes…

1. Low Battery Charge

A blinking light often signals a low battery charge, indicating that it’s time to power up your chair.

This usually occurs after prolonged use or extended periods of inactivity where the chair hasn’t been charged, leaving the battery drained and urgently needing recharging.

2. Motor Wiring Faults

When the lights flash, it could indicate a wiring issue.

This problem often stems from incorrect installation or wires becoming loose over time.

In fact, inspecting your chair regularly can ensure all connections are secure, preventing potential short circuits and ensuring the motor operates efficiently.

3. Overvoltage Supply

Too much power can also cause the lights to blink. It’s a silent alarm telling you the power supply is too high.

When the Jazzy Power Chair receives an overvoltage supply, its lights will blink to indicate the problem.

Overvoltage occurs when more power is supplied than the power chair can take. The result is a short circuit or malfunction.

This places a lot of stress on the electrical components and may cause damage, so address this problem quickly.

4. Worn-Out Batteries

If the lights keep blinking, it might be time for new batteries. It clearly signals that the old ones are tired and need a replacement. 

This happens when your batteries are very old and no longer hold a charge. You’re using them more than normal, and they can’t keep up with the power demand.

The battery terminals are dirty or corroded, preventing a proper connection to the power chair.

5. Brake Fault

When the brakes have an issue, the lights blink to alert you that something’s wrong.

Knowing this, a brake fault is one of the most common causes of blinking lights on a Jazzy power chair.

A mechanical, electrical, or hydraulic issue with the brakes usually prevents them from working properly. 

6. Poor Connections

And finally, rust or loose connections make the lights flicker. Always check rust and ensure you follow the necessary procedures.

See those blinking lights on your Jazzy Power Chair? Then, check for poor connections. Poor connections can occur due to several factors, including worn wires, faulty electrical components, and loose fittings.

Worn wires are a no-no: they can decrease the current between two points, which can cause the light to flicker or blink intermittently. 

So, there you have it: Each blink is like a secret message from your chair, telling you exactly what it needs. Your job is to listen and take action!

How To Fix?

If you’re confused, turn to your user manual. It breaks down those error codes and gives you the lowdown on fixing them.

But yes, if you’re scratching your head and feeling stuck, there’s no shame in calling in the pros.

A skilled technician can pinpoint the issue and get your chair rolling smoothly. Remember, while some fixes are easy, others are no mean feat…

What they need is an expert touch. Better safe than sorry – you don’t want to accidentally turn a small issue into a big problem!

Now, turn to the next section for the ultimate diagnostics guide…

Diagnosing The Electric Wheelchair Flashing

Typically, there are nine flashing lights on a power wheelchair: three red, three green, and four yellow lights.

Now, for an excellent review, check out this YouTube video from Marc’s Mobility to learn about the different fault codes and how to lock and unlock your power wheelchair:

Here are the issues to look out for as a power wheelchair user.

  1. One light flash (one red) means the electric wheelchair batteries are low. You will need a power wheelchair battery replacement soon.
  2. Two flashing lights (two red) imply that the power chair’s left motor is faulty. You must check on it to determine whether it has a bad connection or corrosion issues.
  3. A three-light flashing sequence ( three red) depicts a motor wiring fault on the left motor, and you have to replace the unit.
  4. A four-light flashing sequence (three red and one yellow) shows a faulty right motor. You have to check for corrosion or if the motor has a bad connection.
  5. Five lights flashing (three red and two yellow) show a motor wiring fault on the right motor, and you must replace it.
  6. Seven lights flashing (three red and four yellow) show a bad joystick controller.
  7. Eight flashing lights (three red, four yellow, and one green) show a controller error. You have to replace the defective brainbox.
  8. Nine flashing lights (three red, two green, and four yellow) show bad park breaks or brake faults.

Nine flashing lights can also show that the chair is in neutral. You will need to put the power chair into gear and turn the power off, and then on.

If ten lights flash in sequence on the bar, you’ve applied excessive voltage to the controller. This rare occurrence signals that the electrical input surpasses the recommended level.

Other instances when the power lights may light up include:

  1. The battery gauge is a warning sign, flashing slowly to show low battery power. So take note!
  2. The battery gauge steps up to show that you have connected the battery charger. This indication shows that your device is getting charged.
  3. The gauge binks at a 2.5-second time rate to show the power chair has gone into sleep mode. You can turn the wheelchair off and on to remedy this issue.
  4. The speed indicator rippling shows that the chair is in lock mode. You must put the joystick into the drive position and hold until you hear a pitch beep sound.

How To Fix: Push the joystick into reverse until you hear another beep sound. Release your joystick, and you will hear a loud beep showing the chair is out of the lock position.

The battery gauge rippling shows that the joystick is in a defective position during the power-up.

To finish, you must return the joystick to neutral and power the mobility device again.

But how do you maintain a non-blinking chair? Scroll to the next section…
