Well, Val hasn't posted very often on MercedesShop but when he does, LOOK OUT!
Being an engineer myself (electrical), I must admit, I had to drop everything and read his post.
I don't know what it is about engineers but, when we are in the presence of someone who really knows their stuff, it's a spiritual experience.
Thanks for the post!
