Generic Tachometer Question

I have a handheld tach with two leads on it: a red lead and a black lead. The red lead should go to the negative of the coil and the black should be grounded right? I know this is basic but I just cant remember.

Any help is appreciated.

Thanks,
Mike.

That sounds right if it has an internal battery in the unit.
