Got a couple questions on this. Does the tach have any evidence of mounting to a instrument cluster around the screw holes? Also, do you have any pics of the back of the tach face? Thanks.

I’ll get inline for this as well

**Joesjunk** · 01-11-2022, 09:32 PM

It sure looks as if was mounted in a truck. So I’m guessing this is used and not NOS?

**Joesjunk** · 01-11-2022, 09:34 PM

You can see where it has been mounted

**62cdan** · 01-11-2022, 09:36 PM

NOS was never mentioned, or implied.
Lets be clear on that.

I was just asking for clearly, It was just misleading with the original box.

Thank you

Mike, do you have way to test the tach with a multimeter or otherwise? I can explain how, it's very easy under a minute.

Dave, can you post how to test the tach with a multimeter. I have an unistalled 8 cyl tach I would like to test. Thanks!
