I believe that indicates a left motor fault

The three light flash indicates a short circuit between the left motor(as you are sitting in the chair)and the battery. Check all the wiring from the control box to the motor and make sure it is not damaged in any way. If it is okay, you have most likely fried the left side motor. A new motor-gearbox assembly for this chair runs in the neighborhood of $1,400.00, or you can take the motor off and take it in for a full rebuild for about $250 or so. Unplug the joystick and remove the seat and cowl. Jack up the left side with both motors in gear. Remove the center nut cover and take off the nut holding on the wheel taking care to retain the key that slides into the groove on the axle. Disconnect the wiring plug to the motor and remove the six bolts holding the motor to the frame. Separate the gearbox from the motor and take the motor to a rewind shop for repairs. Reinstall and it should be good to go.

Did you replace both batteries? How old is the chair? Sometimes the on-off keypad becomes worn and does not make contact with the on-off switch. When charging the joystick lights can light up but after unplugging they should remain on. When you plug in the charger look under the rear cover at the charger you should see 2 lights, one red and one yellow to indicate that you are charging the chair if you do not see both lights lit then the charger is bad or has a blown fuse. Only a Tech will be able to tell what is wrong. If Medicare purchased your chair then they will pay for most of repair costs. Contact your provider or a repair service company

Make sure all of your connections are tights and the your fuses do not need to be replaced.

Blinking lights on the controller usually indicates a problem, the number of blinking lights are used to diagnose the problem. Take a look at this website to identify the type of controller you have on your scooter so you can dtermine what the blinking lights are trying to indicate.

You definitely need new batteries. After that amount of time the batteries go bad and the plates inside become sulfated. They are only good as boat anchors now.
It is a easy do it your self repair. There are 2, Group 22 batteries in this model. You want to get deep cycle sealed lead acid, preferably AGM (advanced glass matt) group 22 batteries.
Flip the seating system back by releasing the lever under the front of the seat.Make sure you do not pinch the joystick wiring at the back when you do this.
Remove the black plastic cover.
The batteries will be secured by a strap which you should unbuckle.
Disconnect the plugs to the batteries and note how they are run, oriented and connected.
Pull out the batteries, one at a time, from the base.
Make the wiring connections to the battery , put the batteries back in the chair, plug everything in and you are set to go. Hope this helps.
