my Tach just quit working. does not move when key turned on, does Nothing when Running. What is there to "Check" before I have to pull the circuit panel off the back of the gauges ??? Thanks. * What years Tach will fit ??? * car is orig 1973 Z28
need to remove my Dash Cluster "Bezel" to change the Speedometer And maybe the TACH. Exactly "HOW" does the wood grained "bezel" come off? ( I believe 4 screws), anything else? any way to "Check" he TACH ? (I see new circuit boards for them on ebay) It just Stopped Working. thanks
If it doesn't move with the key "On"... It's probably a power or ground connection.
I believe a 70-78 tach will work and fit correctly.
You will want one with the correct "redline".
And be sure it's a V8 tach if you do need to replace it. (A V6 tach will read incorreclty.)
