Two Times Can't be a Coincidence...Dart not Firing

You can NOT necessarily show that with resistance checks. Only some sort of dynamic or output test would show that. Since there is no such data, a guy would have to develop a tester, and say, test "a bunch" (maybe 50 or 100?) "known good" pickups to get a baseline.

And that is why I mentioned the dynamic test in my post, with the dizzy out, and spun by hand, with an analog meter reading the output spikes.
Of course you are right, it is highly unlikely that one could ever find a spec, and it's just as unlikely that a member would go out and procure a bunch to develop a test.
But in over 45 years of running, and tuning, Mopes I have only ever had one pick-up failure; and it failed the dynamic test.I stopped carrying a spare many years ago.
I'm not trying to be argumentative, just saying.
