Any electromechanical device requires occasional troubleshooting. However, most problems that arise can usu-

ally 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 Select 14/14XL power chairs. 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 Select 14/14XL 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 Jazzy Select 14/14XL 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.

 If you have an onboard charger, 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 properly-

wired 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 Select 14/14XL 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 Jazzy Select 14/

14XL 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.
