Any chairs are very hard on batteries to start with. Most chairs have a charging inhibit so they can not be operated with the charger connected, so you can't use line current to test. And typical auto chargers will fast charge & cause SLA batteries to leak acid.
I used a trickle charger to charge

As already mentioned the Omegatrac has a one of a kind transmission where one motor is the drive motor and the other motor is for steering. The Liber T controller was specifically designed for this transmission and, unfortunately, is no longer available.
Does your joystick give you anything? Lights, error code or anything to make it seem that it is getting a signal? If not, i would probably look at the cable that plugs into the joystick pod. Be very careful! The plug should have two bigger prongs and 4 smaller prongs. They are very easy to break and will render the chair useless. Not sure if Next Mobility would have any of these cables to sell you or not but it is definitely not a standard connection. I've looked and looked with no luck.
The problem I have also encountered is that the Liber T parts are not all compatible for some reason. I also have one with a broken pod and I thought I could just use the Liber T pod off my other chair but doesn't work. They look exactly the same which leads me to think there must be some differences in the programming that makes them non compatible. I did end up buying a new joystick to put in the busted pod. That got the chair moving but the new joystick must not be quite right. The electronic brakes don't work right and it can give me over voltage errors if I'm not careful.
Feel free to describe what is happening in more detail and I'll let you know if I have any ideas. I do have a pdf of the Liber T control system that I could send you. It isn't anything real helpful but does list what all of the error codes mean. Also let me know if you are interested in selling it either before or after you fix it.
would 1 broken prong really be enough to kill all communication? Pretty silly to build such a tank of a wheelchair with such an easily damaged piece.
