Need (1) switched 12V to power it (2) black wire to ground (3) sense wire to coil neg primary post (same for points or electronic (black/yellow wire on the pentastar ECU pigtail for electronic). (4) another wire for the front face light. if 1 2 & 3 are OK then the tach is shot. EDIT I am assuming not MSD

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)

Also note, some of the 66 or 67 console mounted tachs have a seperate unit that goes with it. In other words , it's a two part deal .It's a round disc shapped sending unit if I remember correct. This may or may not be true on the '67 , just thought I would throw that out there .
Greg
I thought only the 66 tach's had the separate sending unit and the 67's were inside the tach?
