Wall outlet bad? Charger not turned on/plugged in right? Something disconnected? Bad battery connection? Blown fuse in chair or charger? Bad battery or batteries?

Something between the batteries and the motors and joystick is interrupted. Recheck fuses and connections.

the meter is an amp indicator, therefore wired in line with charger, if batteries are charging and meter is not indicating then the meter is bad. if batteries are full then it will move very slightly when batteries are low it moves more

when you plug in the charger do you get any amp reading on the meter located at the rear of the chair near where the charger cord plugs into the chair. When you plug in the cord the meter should deflect and read 6 amps or so. If you aren't getting any deflection of the amp meter then either the batteries are dead or the charger is bad. If you have a voltmeter you can set it to 200 volts dc and plug the leads into the charger port located under the front of the joystick Plug the leads into the 2 outter holes of the port with the charger plugged into the wall you should be reading 27-30 volts. Unplug the charger and you will be reading the battery voltage and fully charged they should read 25-27+ volts. If you aren't reading 25-27 volts without the charger plugged in you will need new batteries( anything less than 10 volts will not let the chair turn on) if you aren't getting 27-30 volts with the charger plugged in then the charger is bad and you can get or borrow an off-board charger and charge the chair thru the joystick port Hope this helps

Cathey when you plug in the charger look at the rear of the chair at the meter if the chair is charging then the meter will indicate some amperage reading when it is fully charged the meter will read zero. Also turn on the chair and if the lights are scrolling or flashing it shows that the charger is plugged in. Now if after the meter reads zero (if it ever does) the lights on the joystick should all be lit indicating a full charge. If you aren't getting all the lights and the meter indicated the charger was working then you need to replace the batteries Hope this helps

You'll have to get to the battery terminals while they're charging, and then you can measure the charger voltage, if any (around 12 v).
It sounds like your charger is bad, and you can order one from this site:

Good luck, and hope this helps you.

Does all your lights on the joystick come on after charging? If you can have someone look behind your chair while still plugged in for charging, the green light on the charger will be lit if the batteries are fully charged. They will have to kneel and look under the shroud to locate the charger they will see the light if it is on. Also check the meter on the rear of the chair the meter should read zero when the chair is plugged in and fully charged. I fyour chrger is working then if the chair does not stay with power for what was normal then new batteries are probably needed

1st Check the 25amp inline fuse located behind the volt meter. 2nd Check the 50 amp fuse located behind the foot rest. A pin located under the foot rest when pulled out will open the front to access the fuse.
