Stock peedometer how does it work
I know the stock speedometer is wired to the white wire on the stock controller. Does anyone know how it calculates speed from that wire. I recently installed an 72v infineon controller(ecrazyman) and the blue wire from the new controller doesn't work with the stock speedometer. I have read on another forum that this blue wire works off a hall sensor and actually can be used with a cycle analyst computer to determine speed. So how does the stock controller determine speed with the analog gauge in the front dash.
It doesn't work well at all, so I wouldn't work on trying to reconnect it.
Unless I am mistaken, it is simply a value that is internally calculated by the controller depending on voltage and current used.
