A funny thing happened after my last story about troubleshooting a no-crank condition. I experienced a no-crank condition.

Love it and the sketch drawings too Rob! These things have always been a mystery to me, not any more! I have a Porsche 911 with turn signal troubles, where the relay burns up when I try the signal (either way). Now that I understand how it is operating, I suspect that the 4-way flasher is the culprit. Anybody else have an issue like this?
