  • Electrical: 1957 Golden Hawk Tachometer

    The 57 Golden Hawk Tach is not working. Just a look under the hood shows the sending unit between the cap and distributor is there but I am not sure where to start looking. What connections should I check first? I know how hard it could be to find one if it is shot. Some chapter member suggested using a different sender. Thoughts on that? Having a 3 speed overdrive and the low rear end and T-85, I would feel comfortable to have a tach reading out. I don't plan on winding her up but it would be nice to figure good shift points. Supercharger is unhook and frozen. The car has a 1958 289 and pulls strong at any rpm.

    Thanks for your imput.

    Bob, the good news is the '57 GH 289" usually floats the valves before 5,000 RPM and thus is very difficult to blow up.

    But the bad news is the Stewart-Warner synchronous drive tach is a clunky and temperamental conglomeration. There's the sending unit in the distributor, the NLA wiring harness, the synchro motor and the tach head. I've repaired a few, but these days, I just convert them to electronic guts.

      The obvious first thing to check would be the Cable connections at the Tach. and the Signal Generator device on the Dist.
      There are No 12V "Power Wires" or ANYTHING to test.

      I would think beyond that, it would take a Professional Corvette or "Other" Make SW/GM Delco Tach. Pro to actually fix either unit or the Special "Cable".

        Stewart Warner still makes a gauge that looks almost identical. No crazy senders needed. You could use that and still route the old cables and keep authentic look.

          Gotta get on that supercharger. It's what makes a Golden Hawk "golden"... plus the sounds and the feel of forced induction!

            This is the modern SW tachometer. No sending unit needed.

              Looks like it belongs there.
