Hello,
I have one of those elderly infineon controller, repackaged by the german seller ebs. Worked fine but my new front hub motor was running backwards. So I went through the trouble of figuring out the right phase / hall combination, when it suddenly stopped working. No idea what went wrong - probably a short somewhere that fried a crucial part. Did a few tests and noticed that all low voltage pads (+5V) show half the supposed voltage at around 2.5V so I guess the 12V to 5V rail is broken. How can I find out where exactly the problem is ?
