Tachometer Fluttering at 55mph

That is Terrific. I am still learning on this site and haven't discovered all it has to offer.
Thank You very much.

The Archives are probably commonly overlooked. Every now n then, you can find a pretty good kernel of info there.

KZR Archive

I am gonna take a look now.
Thanks

Update:
I found the Troubleshooting Guide for "Tachometer pointer fluctuates" lists some checks to be made in the electrical system.
Thank You again for pointing me down the electronic avenue!
