Re: My letter to Newtronic support - your thoughts?

Intermittent coil problems are one of the hardest to troubleshoot without using the "replace it to test it" method, which can get expensive. Glad you got it solved!

And remember, I'm still really a newbie in a lot of ways - never really turned a wrench until I got my 400 3 years ago, so I'm still not that good at spotting the obvious sometimes.
...but what truly made the light go off (pun intended) in my head was: When I was setting the timing for the millionth time with the timing light, I suddenly realized that the light wasn't blinking perfectly steady. It seemed to miss one or two every once in a while, then it would miss every other one for a series of maybe ten or so. I tried the timing sensor on both plug wires and the result was the same (again, only when the coil warmed up a bit). Mind you, since the ignition was Newtronic, and the wires had been replaced, it really couldn't be anything else. I was so pissed at myself for never really *seeing* that before, even though I've probably seen it a hundred times.
Again, thanks to all you guys for all the advice and time spent on this problem.
EDIT: I think I'll rename this thread so it better reflects the outcome...

Yes, the strobe timing light is good for a lot of things other than setting timing. It also exposes false triggers in an electronic ignition system. A false trigger will produce a "ghost image" of your rotor in the wrong position.
