Junk equiss gauges?

Ive had an Autometer boost and Autogauge mechanical water gauges go bad. The Equus tach in my now sold truck would work then quit.

Yep. My tach glitches for some reason too, now that you mentioned that.
Damn it! I hate replacing new stuff. Those Stewart Warner gauges were good ones tho. About the best that You could get, back in the ole days.
Another issue is when they are new but sat on the shelf for a year during the build.
