Hi, I'm currently running an older powabyke euro,not exiting but suiting my current needs. Unfortunately a long period of intermittant electrical faults have finally merged into failure. As a stopgap I am running it on 24v with a simple on/off switch, which doesn't blow fuses as long as it's moving before I throw the switch! What I need to get a bit closer to the original system is either a wiring diagram, which for some reason seem to be as rare as common sense, or a simpler motor speed controller that would work with the powabykes existing throttle. I would be happy with plans for a controller that could be soldered up by a relative novice but don't have enough know how to design one myself. Any suggestions gratefully received,
