Have jet 3 power chair about 9 years old but has not been used much has set alot when i charge up the batterys it goes in circles only one motor is working i think could it be the batterys or what

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.

Check your freewheel levers are in drive mode.

check the motor brushes if they are 1/4 inch or less replace them. Next, after driving the chair for a while check the motor casing near the brake assemblies on the rear of each motor if the casing is hot then you have a sticking brake pad or pads and this can cause the excess battery drain. If you have sticking brake or brakes unfortunately the whole motor assembly will have to be changed Hope this helps

Get new batteries If your batteries are 2-3 years old its time for new ones. You can check the output of the charger by using a digital voltmeter Set the meter to 200 vdc and plug it into the two outter holes of the charger port with the charger plugged in you should read 27-30 volts. and with the charger unpluged you can aslo read the voltage of your batteries. fully charged they should read 25 -27 volts. If when charging you don't read 27-30 volts then the charger isn't working and you can get an offboard charger cheaper than the onboard just charge thru the charger port on the joystick. Hope this helps

Mark Batteries your charger is putting our enuf 13.15 volts for each battery so after charging all night you should be reading about 13 volts on each. If your batts are only 12 volts after all night charge then batteries are weak Hope this helps

papa you don't give alot of information to try to guess what is wrong. How old are the batteries? If 2 years or older probably time for new ones. Is the charger working correctly? Does the yellow light turn green after charging overnite. If not it could be a bad charger. Of course it could be both time for new batteries and a new charger My best guess is that you need new batteries. If Medicare paid for your chair then they will pay for most of the cost of new batteries. Youe chair uses 2 U1 batteries and if there is a battery warehouse or store in your area they should have the batteries also check for an Interstate store that can get you the batteries. Hope this helps

Are your batteries fully charged? Are the batteries 2 years old or older? Even with a full charge older batteries will not generate amperage to make the chair go as fast as when new. Also the motors tend to slow down with age due to brushes wearing down. Now, if the batteries are new and the motors are not that old then you need to find a wheelchair provider that has a PP1 programmer and have then check the settings for forward speed etc. If the speed is not set to 100 then they can increase the forward speed to 100%. Hope this helps you

Hi. A voltage of 34 volts is way to high. Most chargers are limited to about 28.5 volts. You will quickly dry out your batteries at 34 volts. I would say your charger is very faulty.
You have probably already destroyed your batteries at that charge rate.
Are the batteries new or a couple of years old.
I serviced a machine last year, that, according to the owner, had been through 6 sets of batteries in 4 years. His charger had the same problem as yours.
Good luck. Neil.
