Need tach help, please!

I have a factory tach in my 70 chevy and it doesn't work. I have the brown going to the neg on the coil and the pink going to the fuse box. My test light says I have power all the way to the end of the harness where it plugs into the tach on the back. How can I check the tach to see if it is good or not? thanks
