Got a national wheel-o-vator lift that’s not running - model BC60, screw drive installed around 2012. Lift was running previously, although ran rough.... ran a few times then it would shutdown. Returned now and it’s shutdown and not moving at all. Safety circuit looks good, power ok, transformers and rectifiers good. Can’t get it to run still though, won’t even run off the board. I have pictures of the schematics and data plate but it won’t let me attach them (I assume since I’m doing this on my phone).
