Hey everyone, I am in the process of converting the scooter. I am at a crossroads when it comes to the stock dashboard. The dash, lights, brake, and throttle all share a common +/- bus. This leaves 3 signal wires for the throttle, brake, and dash. Does anyone have any knowledge as to the pinout of the dash plug? I have identified the first pin to the left of the notch as ground, the next being the + bus. I connected the +/- busses to 5v to see if the dash turns on and got nothing, so either the dash requires a different voltage (such as 12v, or maybe even 36v), or the dash doesn't turn on until it recieves a signal through the signal wire.
The problem is I do not know what kind of signal this would be. I assume it may just be 5v but I don't know for sure and don't want to fry anything. My other theory is that the signal for the dash is straight battery voltage which not only turns on the dash but it also allows the dash module to determine the charge level of the battery. However there also is the problem of speed limiting. Because the throttle signal runs through the dash it's entire possible that the dash is what does the speed limiting of the stock bird.
The best way to figure this out would be to take apart a functional scooter and probe the pins to see what voltages it's running.
