I have not had much time to look at the tach. I did slide a wire through the panel and touched the needle on the tach and it will easily move and stay anywhere that you push it to. Yes, I tapped it, checked the fuse and connections at the coils..........and that all looks good. Guess now I need to pull the cluster and check to see if I am getting power and grounding correctly. I got my Ford CD Manual today............and loaded it on the computer, so I guess I will jsut go through the diagnostics. By the way........that manual is awesome from what little time I had to look at it today. (factory tech manual for 93-94 Mark VIII and others.......bought on ebay for $10)
