I have a 1982 Stingray with a Mercruiser 120 and MCM 120 Stern Drive. I
just replaced the points type ignition with a Delco EST and have some
questions about the shift interrupter (which I cannot seen to find). The
timing instructions tell you to short the shift interrupter as part of the
process. I traced the wiring as shown in the service manual and found two
wires (gray and black) with ring terminals that are taped off but no
terminal block or switch. If I connect these two terminals, it kills the
engine.. Does this engine/sterndrive combo have a shift interrupter?

Thanks,
Patrick
