Battery charger on board doesn't work. Replaced everything, stil
Replaced the batteries AND the on board charger, but the unit will not charge w/ on board charger. As soon as I plug it in, the "charge full" light comes on. I currently use 2 car chargers to keep me mobile. Can anyone help with where to look next? The on board meter does not move when pluged in where it did in prior weeks. Help!

Either charger has an issue or new battery is boogus. Check charger output for specs. Subject battery to a few discharge/charge cycles. If charger is definitely good and battery will not charge fully after a few cycles then you have confirmed that new battery is bogus.
Its unusual for a charger that was working to stop working because you replaced the batteries. Does your chair operate correctly with the new batteries? If so then I would check the connection of the on-board charger at the controller box located in the front base section ahead of the batteries. Trace the cable from the charger to the controller and make sure it didn't come unplugged from the controller. Your red light on the charger would still light up but you would never charge the batteries. Now if you can locate an off board charger (borrow from a friend or neighbor that has one or borrow one from your local provider) plug it in the charger port located under the front of the joystick and see if the batteries will get fully charged that way. If you can't find any cable problems with the on-board charger and the off-board charger charges the batteries then there is a problem with the on-board charger or the charging system through the controller. It would be cheaper to purchase an off-board charger if the borrowed one works than try to replace the on-board charger. Hope this helps
Since you have already replaced the battery and the laptop works with
the AC charger, then probably the charge circuit in the system board (mother board) is bad. I have rarely seen an AC charger that will power the laptop but not charge the battery. 99% of the time, if it is not the battery, it is the system board.
My charger has a fuse located on the circuit board inside the unit....when mine stopped working, it was the fuse...replaced it and it is working fine for one battery, the other blows the fuse every time....bad battery.
