The serial number begins with the letter J and is found on the main frame of the power chair near the batteries. It may also be found on the seat post if the unit features a clover leaf style.

All serial numbers for Pride products are 14 characters long and are shown on a white sticker.

Hi Gloria,
The first thing you need to do is measure the voltage at the charging socket of the Joystick (outside 2 pins). This will determine a lot of things, so I can guide you further.

There is a sequence of a button push while moving the joy stick in a certain direction untill it beeps. Check the owners manual for the exact sequence. You can download the manual from Pride's website.

You have to disconnect the charger in order for the chair to move. It automatically removes power from the controller while the batteries charge.

Not a good idea to buy USED power chair batteries. Even new ones just have a 3-4 year life span. But yes, you can buy used batteries.

You will have to take it to a mobility dealer to have it programmed

Put the chair in free wheel mode and then back again and then turn the chair off then on again. Sometimes the chair will get out of gear just a littel.

Here's a link to Pride Mobility, maker of the Jazzy wheelchairs. This takes you to the Select 6; there's also a Select 6 Ultra. Just click on models and it will display all of their line of equipment.
