This was at the beginning of my chasing down an electrical problem. I am not sure if the Alternator relates to the coils or not. But I do know that zeroing in on anything electrical is tricky. That is why I am angry and reporting all of this.. Ford should have provided a fix and a recall for the coil problems. I like Ford, but even when you pull over to safety on an Interstate, there is still a danger of someone plowing into you.
