Sure you didn't get it backward? The resistance from the secondary to common ground is LESS than the resistance to the primary tap because the latter includes both the secondary resistance and the primary resistance. The points should attach to the lowest resistance tap. However, with a 50:1 winding ratio, I am skeptical as to whether you can see the difference on an ohmmeter. 2% of scale if windings are same diameter (and usually they are smaller on the secondary making this measurement even harder to see). Probably one reason why they are marked. I too appologize for complicating what looked like a simple question. However, this isn't a simple question and debate like this adds to our understanding. For the practical, there were several references to the idea that although one way is better, either will work. So, we can debate correctness while Mack fixes his tractor.
