What Scott was saying is that the ignition switch can be good in the ON
position but fail to keep the connection when you turn it the rest of
the way to START.

The "ignition switch" is actually 4 switches inside that do different
things in different positions. The critical ignition/fuel injection
black wire contact is supposed to be ON in both the ON and the START
positions.

If you reliably get spark when using the key switch to crank the engine
you can assume the ignition switch black wire contact is working in the
START position.

Then, still connected, I pinned center wire of Hall sender connector (at distributor) to ground. I heard a "click" in the distributor (my conclusion (right? or wrong?) is that the Hall sender in the distributor is OK?).
