Hi,

I have a 9 volt battery powered dwell/tach meter that only has two wire contacts( + and - )
Do I need more connection wires to get a proper reading?
I know this is a super basic question. I just cant find the basic info for where to connect the wires.
In the dwell meter booklet the diagram for a typical ignition coil has both a positive and negative contact nut for the wires to attach to. MIne only has one nut, which I'm assuming is the negative. The other would be the wire coming out of the ignition coil that connects to the top of the distributor cap.

My friend had explained it to me but I have forgotten. All I can remember from his advice was that one of the wires needed to attach to the stud where the condensor is fastened to the side of the distributor. Perhaps that is an inaccurate memory. Nevertheless, from what I thought I remembered, I hooked up the red wire clip to the one existing nut on the ignition coil and the black wire to the stud that the condensor is fastened to. I did not get any reading.

Thoughts?


Thanx,


J
