    I have a 1978 Post with 6-71 ( non -turbo) and the port side tach quit working. I replaced with new tach and still not working, not getting a signal to it. Anyone ever have an issue like this? I’m sure with some tracing the wire down I can figure it out, was hoping someone may have had this issue before.

    Is it getting feedback from the alternator?
    Quite common.
