Thank you for your help. I replaced the red wire. I met this really wonderful pro that sold me the wire with the silicone casing and I learned a lot. I even got to tour his workshop which was absolutely amazing with enormous lasers. Anyhow, I finally got the wire reconnected and test run, it is still arcing somewhere and the light in the front does not work and the files do not send over correctly. Wow, any advise on this new issue?
