				 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?
