Well I already called Garrett and Sue is sending me a new coil. I hope that this will solve the problem I'm having. Everything in the housing unit seems to be in working order, but it will not ground balance or pick up anything metal. If I turn it on in my vehicle it will bounce around as if I was in a heavily EMI'd area. Only when the vehicle is running though. Any Ideals would be great help. I'm praying for you John, and may the Lord be with your Family.
