Can anyone give me a hint, how I:
- Test the rpm signal on the distributor?
- Bench test my tachs?

I seem to remember this being discussed in the past. I don't remember if anyone ever figured it out. I guess my car has the older style so I can't help.

Maybe someone in Denmark has a tach like yours. You could compare them and tell if yours is good or bad. Good luck.
