12V seems high for a tach singal no? on other cars I've seen it's like ~5v.
I was measuring the voltages on the harness that plug into the ignitor,
and on the wire that is supposed to connect the tach (reffered to as "combination meter" in the factory manual) I was picking up 12V!
Also, doesn't the ignitor send the signal out to the tach? and NOT from the tach to the ignitor?
If so, then shouldn't there be NO power on that wire, when the ignitor is removed???
looking at the diagram there is no indication of voltage or direction of current flow; at least to me, maybe one of you guys can read it better
