Tachometer doesn't work

[Ryan Wright]

Hi Marty,

Thanks for the reply. We need to get together one of these days,
considering we're practically neighbors.

I guess I'll have to dig into my engine's documentation to see if
there is information concerning the tachometer connection point. If I
knew where to find that on the engine I'd at least have a place to get
started! Tracing the wire will be my first priority; if that's good,
then I'll fire up the engine and see if I'm getting a signal directly
from there.

I don't suppose anyone has a diagram of the tachometer system?? Would
be nice to know where the wires go, where any fuses or relays are,
etc.
