I just purchased a 2012 48v txt and had it programmed for 19mph when I picked it up. The batteries needed to be charged but it seemed to run fine when I got it home. I fully charged it and now it won’t move if I floor it. If I ease into the throttle it runs well as long as I don’t push it the last 3/4 of an inch or so. If I do it kills the throttle. If I ease back into it it takes off again. Any help is appreciated. P. S. I checked the inductive throttle and seems fine. I’m thinking programming problem but looking for opinions. Thanks.
