After 2 or so hours in my motorized chair the bars diminish rapidly on control head. just got new batteries & replaced control head. could it be motors?

The larger batteries should have made them run for longer on a single charge. They aren't 35 amp batteries, they are 35 amp *hour*. 12 volts is the thing that matters. Check the batteries are correctly fitted and make sure the motors are clean. The fact they go down faster is puzzling and for that, I would exchange the batteries as they sound faulty.

Answer Edited for clarity. However, the motors are now the issue.

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.

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.

Absolutely. Let me explain what "Ah" means. "Ah" stands for Amp Hours. A 32ah battery will run a 1 amp motor for 32 hours...or a 32 amp motor for one hour...a 16 amp motor for two hours etc.. As long as the battery voltage is the same it's absolutely fine. As long as your chargers are the correct voltage, they'll be fine as well. So basically, the higher the "Ah", the longer the battery will last. This is why higher "Ah" batteries are more expensive. Hope this helps : )

well if u need the charger on then batterys are dead and need to be recharged,or have the batterys checked make sure they are ok by testing a load on them at a local auto parts store for free,if no good make sure u get same type of battery and make sure it is a gel battery not a acid battery

Without the charger the batteries would go dead. You could put a voltmeter across the batteries and you should read more than 28 VDC while charging.

One of the most common controllers, codes to help you and others.





VSI & VR2 Joystick error flash codes:
1 RED BAR:Low Battery Voltage The battery is flat (more likely).
Or the battery has a bad connection (which is unlikely)
2 RED BARS: Left Motor Disconnected The left motor is disconnected. Check all the connections for physical disconnection or corrosion or burning usually caused by the salt poured onto the roads every winter.
3 RED BARS: Left Motor Wiring Trip The left motors wiring has a short circuit. Check all connections and leads for wear and chafing between the left motor and the battery cables or chassis
4 BARS: Right Motor Disconnected The right motor is disconnected. Check all the connections for physical disconnection or corrosion or burning usually caused by the salt poured onto the roads every winter.
5 BARS: Right Motor Wiring Trip The right motors wiring has a short circuit. Check all connections and leads for wear and chafing between the right motor and the battery cables or chassis
6 BARS: Activated if you turn on your wheelchair with an external device like the Charger still connected.
7 BARS: Possible Joystick Trip, Make sure that the joystick is in the centre position before switching on. If you still get this when switching on then joystick is probably faulty.
8 BARS: A control system trip. Make sure that all connections are secure and if so the power module or control pod is probably faulty. Test by substitution of known good one.
9 BARS: The parking brakes have a bad connection or have a failed solenoid, or any lever or switches that disconnect drive for pushing the chair manually may be pulled or switched.
10 BARS: Over voltage detected. This can happen with a bad battery connection although unlikely. More likely your battery charger is faulty and is overcharging your batteries quite severely.
1 BAR to 10 BARS and back in a "ripple" every few seconds. Joystick not cantered when turned on. Switch off and try again.
1 BAR to 6 FLASH every few seconds. System Asleep. Switch off and back on. Time before sleep can be adjusted or disabled in programming

Babble replace the batteries and check out my tip on charging your new batteries. if Medicare paid for your chair then they will cover most of the cost of new batteries contact the provider that sold you your chair and ask if they can change the battries for you Hope this helps

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.

Absolutely not. Higher amphour batts don't put out more voltage, just more voltage longer.
The 2800 takes U-1 gel cell batts that run about 33 amphours...good for about 12-16 miles. You might be able to fit bigger batts in it, but measure first before you buy...gel batts are pricey.
