Pride Mobility Jet 7 Owner`s manual

BASIC TROUBLESHOOTING INSTRUCTIONS: JET 7
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.

BASIC TROUBLESHOOTING INSTRUCTIONS: JET 7
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.

BASIC TROUBLESHOOTING INSTRUCTIONS: JET 7
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.
