Thanks for the info. It confirmed some of my thoughts. I will check the wiring just to make sure. Would the OBC being out effect anything else? I see that it controls the voltages.
what about reverse buzzer, regen, speed kit. I have noticed that when going uphill it really slows down. On flat it runs fine. I expect some slowdown but I think it's excessive. I may have to open another thread for that.
I'm just trying to decide if it makes more sense to replace the OBC (if it would affect anything else) or get a smart charger. I prefer the smart charger option.
