I remember that the carbon lost the conduction after a time and there was a carbon spray laquer, conductive, to be applied. As I also remember, the carbon in SDX was not flat at the bottom, it stood on little legs to create a small space between coil/foil and itself. This means: The "switch" was open until the hit of the stick came.
If these small dots were damaged, the unit had something like a shortcut and had to be replaced.
Examine the underside of the carbon: How does it look like? If there are wrinkles, it is broken and causing shortcut. Are these "feet" ok or flat?

Thank you for your advice. That part has been done. I`ve traced back all missing connections with a conductive pen.
Now I`m striving for perfection. Any advice on restoring the upper carbon part to full performance?
