I recently purchased a Dwell-Tach meter it has two leads, a black and red. Which do I hook to the coil and where, it did not come with instructions, but is in mint condition for one made in 1972.......

Black to grnd, red to coil.

Thanks Richard it will be neat to see my RPM's since the Dart doesn't have a tach on it to show them...........

Hmm.... I've always run mine red to coil positive, black to coil negative.
Maybe it's a brand thing?

Been soo long since I even looked at the thing, mine is a three lead meter, so ignore me.
