Dark green to positive side of coil - done and tested for contact,
You say the wire should be on the negative side of the coil not the positive?????
Absolutely (on the neg side). Not sure if it being on the positive side would fubar a good tach or render it (temporarily) inop (till you switch it back correct/I wouldn't think so but I ain't sure) but change the wire to the neg post (your only option) & see what you get. If all (3) terminals are being fed/have continuity then the tach is bad. EDIT there are no dumb Q's, the points or ECU make/break continuity of the pri circuit to ground & that is the "signal" that is picked up/counted & converted to RPM in the tach (more pulses=higher RPM)
