After messing with my controller ebike started going in reverse
I have a ebike controller rated for 48v but my battery is 60v. Because of over heating I decided to cut the controller open, put it in a fuse box, install a couple of fans on the box, and run it like that. So I did all of that, but the motor started spinning backwards. I switched green and blue phase wires and that did the trick. But I would still like to know what I messed up on the controller? I have a second controller and everything works as it should with that one. So I messed up something probably while cutting the top open. Anyone has any ideas? I'm affraid that it will reverse the polarity while I'm riding the bike, which will make me crash. Any help is appreciated.
