Default Tach is on, then off, then on, then off for good

I have Superformance #633 built in 1999. 351 Windson, stroker. 23,000 miles. It has an old style Smith Tach.

About 4 years ago the tach failed to work about 5% of the time. About 2 years ago it was up to 15% of the time. Late last year It went to 100% gone.

I looked for loose wires and checked all of the ground wires I could find to make sure they had good connections, but found no issues.

Do Smith tachs slowly go bad, or do I more likely have a wiring problem?
