BASIC TROUBLESHOOTING INSTRUCTIONS: JAZZY 1107

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 Jazzy 1107 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 Jazzy 1107 seem to be "dead" (controller does not light up when 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 boxes are fully connected to one another and to the power chair.
! 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 Jazzy 1107 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 battery charger lights during battery charging to determine if the batteries are receiving a

charge. If neither battery charger light is lit when the charger is plugged into an electrical outlet and turned on,

then the batteries are not getting charged. If the power light is not lit when the charger is plugged into an
electrical outlet and turned on, then make sure that the electrical outlet is good. If the charge light is not lit when
the charger is plugged into an electrical outlet, but the power light is, then make sure that the battery charger is
securely plugged into the power base.

! 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 char ge.

! 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 Jazzy 1107 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 occurr ed. The Jazzy 1 107 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: JAZZY 1107

What if my Jazzy 1107 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 Jazzy 1107 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 Jazzy 1107 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 battery condition meter LEDs are flashing a fault code. The Jazzy 1107 comes equipped

with either a VSI or FLIGHT controller . Each controller will flash a code via the battery condition meter LEDs
if a system fault is detected.
