Hey Guys,

I have a 68 postage stamp tach that I've had on the shelf for years. Is there a way to test it to see if it works without installing it?

Thanks !

on a regular tach, green to coil (-) primary, black to ground and red to switched 12V but iirc there was a thread way back on your type & the color code or something was different

Yep, it's the small in dash one. Want to see if it's still good.
