Do it yourself

I've been having an issue over the last year.. I have two electric motorcycles, one is a Lectra, the other a home built three-wheeler. But I haven't been able to get them running. I'd get a controller, wire it up according to the instructions, twist the throttle, and nothing happens. Very frustrating, really.

I've gone through several controllers, and I have two alltrax controllers and two logisystems controllers. I wasn't sure if.. each time I hooked up a controller there'd been some sparking, and I wasn't sure if I'd zapped the controller and that's why nothing spun.
