Thank you, Ron. This is an excellent article that explains the charging system in easy to understand terms. It’s always good to hear from the best in the business.

I had Ron rebuild a set of coils for my '25 several years ago which I installed when the car was finished. I’ve driven the car over 5,500 miles, and have never had to remove the lid from the coilbox. I also use a New Day Timer, which to me is the best.
