Hey Phill;

Let me tell you what a gas tank and a steering wheel is for: The gas tank, you put fuel in your car so you can go for a great drive. You use the steering wheel to point the car in the direction you want to go , "so you can enjoy yourself". This is not mechanics school.
We have a high tech induction oven in our home. More sensors than you can shake a stick at. None of us, but technicians, know anything about them. We turn them on, cook, eat and enjoy...... just before we go for a drive.
I am done with this thread as well.
