Hi all! Been working on my diy ebike. Replaced controller and thumb throttle cause it had begun to run backwards out of the blue, the 1000 w 48 v hub crawled out of the dropouts and.proceeded to rip and bind the hub cable to a bloody ruin
I fixed all that damage, replaced parts, the bike ran perfect then inexplicably began to cut out under power load conditions.
Took it up off the load and it has begun to run backwards again.
Bad hub?
This is why I changed out everything I did.
Ran and worked perfectly fine for a while
Thought I had fixed it. Nope...
I have a dual
 
Sounds like you have the self learning jumpers of the controller connected together. Which will constantly switch between forward and reverse on the phase combo's. You typically only need to plug this together once during first tests then once it is set running the correct direction you unplug it for safety
