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 614 and Jazzy 614 HD power chairs equipped with Dynamic
controllers. 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 614/Jazzy 614HD seem to be “dead” (no lights when the on/off key is pressed)?
Make sure the batteries are installed and wired properly.
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.
Why does my Jazzy 614/Jazzy 614HD travel less distance than it used to on a full charge?
Determine if the batteries have ever been replaced.
Batteries over a year old might be worn down and less
effective.
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 overnight 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 at least 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.
Determine if a wall switch controls the electrical outlet used for battery charging.
If so, the batteries will
not fully charge if the wall switch is turned off inadvertently.
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 an extension cord could 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 too low (into the red), the overall life of the
batteries will be reduced.
Determine if the connections on the battery terminals are tight and secure.
A loose connection at the
battery terminals can cause a loss of voltage in the system.
Determine if the connections on the circuit breaker are tight and secure.
A loose connection at the circuit
breaker can prevent the Jazzy 614/Jazzy 614HD from operating.
Determine if the motor brushes are properly installed and not overly worn (if you have access to the
motor brushes).
Missing or worn motor brushes can cause an increased use of voltage while driving.
