CTL 26 E failure

[MarinusKodde]

My secondhand CTL 26 E has stopped running. I have power coming into the circuit board and I checked the motor brushes. They are ok. Now I am out of further ideas. Does anybody have access to an electrical diagram?

Any solution on this? Seems like I have the same trouble coming up yesterday.
