M42-Minolta AF adapter problem. Little help please!

[Rhodes]

A few time ago I bought a adapter to use my only F/1,4 lens on my minolta dynax 7. The lens is a m42 thread, and so after I got a adapter to use on my X-300s, the next step was to use also on my AF camera.
I bought one with a focusing chip. After receiving it, I try out and had no problem. When I decided to use it, I put everything in place and when switching on the camera, I got a crazy sound and the camera does no work. A friend of mine told me that the adapter is causing a short-circuit, do to a metal part of the lens is touching some part of the camera. To try to see what part and isolate with some transparent fingernail varnish and not use the lens+ adapter in the camera do to the danger of burning the electrical engine.

Correct his idea? What can I do to see what is causing the problem and fix? Or anyone come across similar problem?

Does the camera still work properly with your Minolta AF lenses?

I use a plain adapter without the AF confirmation chip in my Sony digital without issue. I'll try it on my Maxxum later to see if it works okay on that.

Yes, it does!
