Red light on my jet 7 keeps blinking and chair barely moves.

Hi June,
Any electromechanical device requires occasional troubleshooting. However, most problems that arise can usually be solved with a bit of thought and common sense. Many of these problems occur because the batteries are not fully charged or because the batteries are worn down and can no longer hold a charge. Below are a series of basic troubleshooting instructions for the Jet 7 Power Chair. This information is to be used as a supplement to the troubleshooting instructions provided in the owner's manual. If you have any questions about this information, contact your authorized Pride Provider. What if the systems on my Jet 7 seem to be "dead" (controller does not light up when the on/off key is pressed)? ! Make sure the batteries are wired properly-refer to the battery wiring diagram located on the power base. ! Make sure the connections on the battery terminals are tight and secure. ! Make sure the battery quick-disconnect harness connections are fully joined. ! Make sure the main circuit breaker has not tripped-push in the main circuit breaker reset button. ! Make sure the controller is completely connected to the power base. What if the range per charge of my Jet 7 diminishes over time? ! Determine if the batteries have ever been replaced. Batteries over a year old may be defective. ! Determine how frequently you charge the batteries in comparison to how often you use the power chair. If you use your power chair on a daily basis, you should charge the batteries every day for 8-14 hours. ! Determine when the batteries were last charged. Even if the power chair has not been in use, the batteries should be charged once a week for 12-14 hours. ! Determine how long you let the batteries charge. It takes 8-14 hours to fully charge a depleted set of batteries; continual undercharging reduces the overall life of the batteries. ! Observe the ammeter during battery charging to determine if the batteries are receiving a charge. If the ammeter does not go up when the battery charger is plugged into the charger power cord receptacle and an electrical outlet, the batteries are not getting charged. Check the charger fuse and ensure the electrical outlet is good. ! Determine if a wall switch controls the electrical outlet used for battery charging. If a wall switch does control the outlet and the switch is turned off inadvertently, the batteries will not fully charge. ! Is an extension cord being used to connect the battery charger to the electrical outlet? Pride prohibits the use of an extension cord when charging the batteries. The charger should be plugged directly into a properlywired standard electrical outlet as the length and condition of the extension cord can have an adverse affect on the battery charger. ! Determine how far you let the battery condition meter LEDs go down before charging the batteries. If you continually allow the battery condition meter LEDs to fall into the red area, the overall life of the batteries will be reduced. What if my Jet 7 is operating slower than it has in the past? ! Determine when the batteries were last charged. When the battery charge gets low, the batteries supply less power to the motors, which causes the motors to spin slower. ! Determine the temperature of the power chair at the time the problem occurred. The Jet 7 electrical system will protect itself from overheating when its internal temperature gets too high by reducing the amount of power sent to the motors. When this happens, the power chair will gradually slow to a stop. Allow the power chair to cool down and it will resume normal operation.
What if my Jet 7 begins pulling to one side? ! Determine if the joystick is being deflected straight or at a slight angle. Even a small amount of deflection right or left will cause the chair to veer over a long distance. ! Determine if both manual freewheel levers are in the drive position. If only one manual freewheel lever is in the drive position, the other motor will not operate and the Jet 7 will veer severely. ! Determine if both tires are inflated to the proper psi if the power chair is equipped with pneumatic tires. Pneumatic tires should be inflated to 35 psi (2.4 bar). If one tire is inflated more than the other, the power chair will pull to the side that is underinflated. ! Determine if the caster wheels are pivoting freely. If either caster wheel is not pivoting freely, the unit will veer to the side. What if the Jet 7 powers up, but will not move? ! Determine if both manual freewheel levers are in the freewheel position. If the power chair is in freewheel mode, then the electronics will function but the motors will not spin the wheels. ! Determine if the controller is flashing a fault code. The Jet 7 comes equipped with a VSI controller. The VSI controller will flash a code via the battery condition meter LEDs if a system fault is detected.
# OF LEDS CODE CAUSE POSSIBLE SOLUTION One red LED 1 Low battery voltage Charge batteries Two red LEDs 2 Left motor open Make sure left motor is plugged into controller. Three red LEDs 3 Left motor wiring fault Contact your authorized Pride Provider. Three red LEDs 4 Right motor open Make sure right motor is plugged into controller. One yellow LED Three red LEDs 5 Right motor wiring fault Contact your authorized Pride Provider. Two yellow LEDs Three red LEDs 6 Inhibit active Contact your authorized Pride Provider. Three yellow LEDs Three red LEDs 7 Joystick error Contact your authorized Pride Provider. Four yellow LEDs Three red LEDs 8 Controller error Contact your authorized Pride Provider. Four yellow LEDs One green LED Three red LEDs 9 Brake fault Make sure both motors are plugged into controller. Four yellow LEDs Two green LEDs Three red LEDs 10 High battery voltage Contact your authorized Pride Provider.
What if the speed LEDs on the 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, an internal charger inhibit feature keeps the power chair from driving. This is indicated by the 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. What if the speed LEDs on the VSI begin to scroll? ! Determine if the VSI has been placed in lock mode. The VSI is equipped with a lock mode feature that prevents unintended use of the power chair. If the VSI is in lock mode, deflect the joystick full forward until it beeps, and then deflect the joystick full rearward until it beeps. The joystick should go back to the drive function.

When the red light is on it is to indicate that the charger is getting power from the wall outlet. If there is a second light that normally comes on Green when charging pay close attention to it when you first plug the charger in. See if it blinks even once then turns off. If it does that means the charger is not seeing any battery voltage at the plug that goes into the chair. If the green light does not blink at all then it usually means the charger is defective. Also most wheelchair battery chargers will not charge the batteries if the chair is to dead to even turn on.

The red light is the power light and if the red light is blinking the charger is bad or the wiring is bad on the chair or the batteries are bad. Usually it's the charger.

you will need a off-board charger to charge the chair Strege Mobility

when you plug in the charger do you get any amp reading on the meter located at the rear of the chair near where the charger cord plugs into the chair. When you plug in the cord the meter should deflect and read 6 amps or so. If you aren't getting any deflection of the amp meter then either the batteries are dead or the charger is bad. If you have a voltmeter you can set it to 200 volts dc and plug the leads into the charger port located under the front of the joystick Plug the leads into the 2 outter holes of the port with the charger plugged into the wall you should be reading 27-30 volts. Unplug the charger and you will be reading the battery voltage and fully charged they should read 25-27+ volts. If you aren't reading 25-27 volts without the charger plugged in you will need new batteries( anything less than 10 volts will not let the chair turn on) if you aren't getting 27-30 volts with the charger plugged in then the charger is bad and you can get or borrow an off-board charger and charge the chair thru the joystick port Hope this helps

Hi valentin 201
I have owned my own business for 3 years and have been working on scooters and powerchairs for 15 years. . In the future give as much info about the scooter as possible.

1. load test the batteries even if you think they are good, check anyway. Sometimes even new batteries won't hold a charge.

2. Your charger on the powerchair must have enough volts to open the charger inhibitor. That is, the charger won't even start up if your batteries are low. Both batteries need to have at least 20-22 vdc.

3. Some chargers have a 3amp fuse check that and repace if needed.

4. With a multi meter set on dc200 check your batteries. Red on one battery and black on the other. Check to see what you get for voltage. If no voltage reverse the lead wire to the other posts. Once you get a reading of 20+ volts watch the meter and plug in the charger, it should increase the volts on the meter. if not the charger is bad, replace. Charger should be 24-31 volts to be a good charger.)

One of these sugestions will fix the problem

Good Luck
Tim

the batteries are not charged and need to be replaced. The reason you have lights is because the charger is supplying power to the chair and the chair will not move when the charger is plugged in because of the inhibit function. Replace the batteries and make sure you charge before use Hope this helps

I am assuming you have a Jet 7 with a VSI controller (manufactured by Penny and Giles) with a steady flash of all the speed and profile LEDs (lights). This is a no drive away feature of the VSI if the charger is plugged in. The older Penny and Giles controllers indicate the same flash code.

If you have an on- board charger check to see if it is plugged into the wall. If it is, unplug it and see if the chair runs. Sometimes, you have to remove the back cover and unplug the charger haress at the output of the charger inside the electronics housing (much more difficult). A failed on-board charger can inhibit the VSI controller (no drive away) even if it unplugged from the wall outlet. There is also a charger inhibit harness with a fuse that might have failed. A qualified technician can jumper this harness to bypass and test.

If you have an off-board charger unplug it from the wall or unplug it from the charging port in the front of the VSI. If the chair runs in either case you have a bad charger.

You may also have a bad VSI controller which can be rebuilt or replaced. Start with the basic charger unplug tests and then work your way to the VSI controller. Hope this helps.

sounds like a charger inhibit problem. Whenever you charge your chair the charger inhibit shuts down the chair so it can't be moved while charging. If you are getting this then that function is not working. Lets try this if you know of someone who has a chair or scooter with an off-board charger see if you can borrow it. Plug the off-board charger into the charger port located under the front of the joystick (don't have the on-board charger plugged in) and then turn the charger on. turn the chair's power on and you hopefully will see the lights blinking again indicating a charger plugged in (charger inhibit) the lights on the charger should be red and yellow (yellow turning green when fully charged) If you still get the problem with the off-board charger then your problem is in the controller or power module and this requires a new one. If Medicare paid for your chair you can call Repair Xpress @ 1-877-81-3733 or Roadrunner Mobility @ 1-800-467-2668 to have them fix it for you and bill Medicare for most of the repair costs. Hope this helps you

Just had this problem with my Guardian Aspire. They had to replace the electronic box with the joy stick. BIG BUCKS!
