Bob,
I believe it has already been mentioned here (CMyles?), but once again: the RPM signal comes out of CPS (Hall Sensor in the dizzy body), then it goes to the ignition amplifier and finally it is paralleled between tachometer, fuel ECU and other rpm receivers.
If your tachometer shows absolutely no activity, then (assuming the tachometers itself is properly powered up) you better check it all the way starting at hall sensor.
Definitely you need to invest into Bentley manual, it's worth every penny they ask for it.
