Default Re: engine analyzer questions

When I connected the black lead to the distributor terminal lead on the coil, with the selector set to the 8 cyl to the tach setting, or the dwell position, and the green lead attached to ground, the needle did not move at all. When the selector was moved to the points position with the same connections, the needle moved approximately 3/4 of the way to the opposite end of the scale which fell in the "open" part of the point scale. As I mentioned, there was no change in the needle position with actual changes in engine RPN. I'm not sure what this " reading " represented. I will try this with a spare 12 volt battery soon and report back. Thank you all for your advice and help
