Don't apologize. Good to add to an existing thread about a general issue which interests everyone. Renewing it keeps it alive. After a time, the photos become archive-only.
Re your question, with reversed polarity, most ignition modules will still trigger and you can adjust the distributor so the timing is "about right", but it won't be ideal because the trigger point will jump around so won't get consistent spark timing. That is because when reversed there is not as sharp a leading edge on the rising part of the signal. I just scrolled up to post #1 by Kit. Didn't you see that clearly explained in his O-scope plots?
