Factory Tach help needed.

I successfully installed a factory tach cluster into my '84 over this past winter and it worked fine up until yesterday when I started it up and noticed it doesn't work anymore. All the other gauges on the cluster still work. I installed an extra tach gauge cluster I had and got the same results. Any info on what could be causing it would be greatly appreciated. Thanks.

Check the plug under the hood for corrosion on the terminals and make sure it's got a good connection. And check to make sure the connections to your coil are tight.

Unless there's something wrong with the wiring, which there shouldn't be, it ought to be just fine. Have you checked all your fuses and the plug on the back of the instrument cluster?

Thanks for the help. Checked all the wiring and somehow missed the fuse when I was fixing other stuff. So I pulled all the fuses and checked them and now its good to go.
