I have been working on Series IV tachometer, which I changed over to neg ground (easy) and attempted to recalibrate for 8 cylinder operation (adjust the pot). I can get accurate readings at either end of the scale, but not both. If I adjust for correct readings at 5000 rpm I get a high reading (1500 rpm) at 1000.
I looked through the Alpine guide, but can find no help there. It seems to be non-linear. I tried resetting the zero point (adjust needle/rotation) to no avail. Any experts out there?
