Hi Steve,

It's pretty hard to debug the wiring without details. I would contact the manufacturer and see if they can give you a wiring diagram. I have done a DIY e-bike with some issues, but had great support from Grin in Vancouver, so it's going fine (except I need a BMS for the batteries I have).

The direct and best way is to inquiry the manufacturer. That is shortcut.
