Gee 2011, I'd think it wasn't a cable driven tach..maybe a signal off the alternator going to the dash( computer ) ??
If everything else on the 'dash' functions fine, check alternator wiring, locate the signal wire, check for pulses.

If it's any help, here's the schematic. 23 is the traveling speed sensor, 24 is the engine speed sensor. I'll do some more looking.

The WSM has all the testing and location information.
It's not a simple system.
