Busted Tach

Hey Guy's,
Is there any way to get my tachometer working again?
I know this is a problem with these cars, just not familiar with how they work.

The signal is generated at the front balancer and converted to DC pulse signal by a transducer mounted into the diagnostic socket. The signal is then used by the tach. If the tach is bad it is usually the capacitors.

With gas cars a bad tach is usually the tach, with your model diesel it is usually the transducer. Unscrew it and move it up an down in the contacts. It is such a low voltage signal that sometimes the contact is poor.
