BASIC TROUBLESHOOTING INSTRUCTIONS: JET 3 ULTRA  
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 3 Ultra 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 3 Ultra 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 3 Ultra 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 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 Jet 3 Ultra 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 3 Ultra 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 3 ULTRA  
What if the left red battery condition meter LED on the GC is flashing?  
! This indicates that battery voltage is very low and the batteiries should be charged immediately.  
What if the battery condition meter LEDs light up left-to-right one at a time in a step sequence?  
! This indicates that the GC is in lock mode. The GC is equipped with a lock mode feature that prevents  
unintended use of the power chair. If the GC is in lock mode, deflect the joystick full forward until it beeps,  
deflect the joystick full rearward until it beeps, then release the joystick. The controller will emit one long beep  
indicating a return to normal operation.  
What if the battery condition meter LEDs ripple left-to-right and the power chair will not drive?  
! 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.  
! Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to  
activate.

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, a 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.
