I have trouble getting an RPM reading at this stage. I have tried both terminals on the coil, and the black/purple tach wire.

The negative terminal on the coil give me intermittent signals around 300-400 RPM while the positive terminal give me readings in excess of 25000 rpm. The Tach wire give me a zero reading. I have scaled the arpm input to a 6 cyl. engine..

Any ideas?
