Need Tachometer circuit wire diagram for the 1983 300D CD TD
 

Not sure I might have missed the ONE link I wanted.

I have the MB 123 repair (2) CD's. They are old (software for 'Netscape Navigator').
They have not actually worked in computer for years. I had a list made up as to which 'numbers' were for the various maintenence jobs. (####.pdf) Lost it. I'm trying to find the #'s for the electric wiring diagram for the tachometer circuit for ''83 D CD TD. Can anybody tell me which # of pdf to view? (with sumartra) Maybe, if I'm lucky, a list of what the various #'s lead to.
