Default Another bad SW tachometer!
This is frustrating. My SW Tach went bad so I purchased another one. I have the dash out of my Cobra for paint, so this looked like a good time to replace it. The SW Tach I received---out of the box with no power, ground or sig connections---reads 1k rpm. It's not at zero with no power.

Damn!

Looks like I need to return this for a replacement.

Unless, of course, this is normal? I wouldn't think so, but anyone know better than I?

I'm just glad I noticed this before I went through all the trouble of replacing it and reinstalling the dashboard.
