    I purchase a reproduction Tach from Parts Place. It came with no instructions, on the back are terminals marked + and S. I am thinking the + terminal goes to the ignition and the S terminal to the negative side on the coil. Is this correct?

    Im not sure about that. I dont know anything about the repro tachs. "S" could stand for "signal" which would go to the negative on th coil. And the "+" might be for key on power

    That seem like the logical choice. I'll go with that.

    Thanks
