I have a wheelchair van that has a remote controlled wheelchair lift. The remote has been repaired several times and the pcb is getting to the point of not being dependable. The lift was built in the 90's and therefore is getting kind of outdated as far as parts are concerned. My question is, would it be feasible to build a remote controller, perhaps hard wiring one instead of trying to make a pcb? The pcb is fairly small as are the components, which means identifying individual ones could be impossible. Suggestions?
