Answer Question
Do you offer any type of repair services on this product?
I have this amp clamp and have been using it for years. Now all of the sudden it doesn't really work. I use it for relative compression testing and now when I zero the clamp I can see it zero out on the scope but when hooked to the vehicle it doesn't show the relative compression humps, just a flat line slightly above zero. If I mess with it and keep zeroing it out and unplugging it and plugging back in, I can sometimes get it to work.
