OK. Thanks for all the posts of your experiences with both the original Ford and the repro. I'll save my money.
I've had my own run-ins with ignition coils. I don't need to continue down that rabbit hole.
I need to point out though a couple of things that are apparent to me in this discussion.
First, the original yellow top IN IT'S DAY was very suspect to lack of product quality. Perhaps that was ONLY because few understood why it was a 9 volt coil to begin with? I'm not going to analyze that?
My issue is getting the tach to read properly using a 12 volt coil, and the combination of CJ advertising his repro coil as 12v rather then 9v and looking original was a great sales hook on me at that moment.
Secondly, no posters have dealt with reporting that the repro failings have long been corrected. I'm not sure how anyone can do that except report that they bought one within the last year or so and have no problems with it. No one has done that.
I do appreciate sincere efforts of posters attempting to help out. However, this is the hard part to say, many of you need to take serious writing courses on how to focus on and illustrate exactly what you mean to say?
Sometimes here I feel like I am stuck in a revolving door on high speed simply because you contradict yourselves, sometimes within the same sentence?
That simply does not help the specific situation.
For instance, you need to know and understand the difference between flammable and inflammable.
