So I'm electrifying this Sun EZ3 recumbent trike for an older gentleman who can no longer drive a car.
I mounted an inexpensive (ebay sourced) 48v/750watt, brushless, gear reduction motor on the rear driving the rear driveshaft via a freewheel sprocket...
I did roughly the same thing a few years ago when I built my 'Kyoto Cruiser' side-by-side tandem and electrified it.
So I mounted the 48v/750watt controller that came with the new motor on the main frame spar above the bottom bracket.
Hooked up the big three blue, yellow, green, wires that run from the controller to the motor. No problem. Hooked up the black wire from the battery to the controller. No problem. Touched the red (hot) wire from the battery to the controller connection and a big spark. Oops? As I didn't have the documentation for the motor/controller at the time I couldn't connect anything else. Now I do have the documentation and have hooked up what I can, but have nothing. Did I screw up? Or are the highlighted portions of the wiring, which has yet to be connected, defeating power output to the motor?
AS USUAL ANY HELP APPRECIATED!
