Hey Paul, thanks for your response and additional info and explanations for others out there. I am familiar with a megger as I was an industrial electrician. Being that I am retired now I don't have access to one. And one thing I did do when I was working is to check the operations or work-ability of items, new or refurbed, before installing them, even though my colleagues mocked me, to verify they were good to go. One of the things that greatly frustrated me was to install an inoperable "new" or "refurbed" item. Anyway, I did replace the latest "bad" coil with a same BWD coil. Car runs like it's supposed to now. I also relocated the coil pack from the top of the motor to get it away from the heat. I suspect that that's what was causing the problem. So far the car is running very well. If you are going to Carlisle I can show you what I've done.
