enough to warm up. In the neutral shifter position, the leaf spring is
not compressed; I can detect continuity across the poles of the switch.

I triggered the switch by hand and nothing happened... no engine stall.
While the leaf was compressed, I checked the continuity again and
(assuming continuity in neutral is normal) expected to see that it was
broken, but it wasn't. So maybe the switch is bad?


I wasn't detecting continuity correctly. I was measuring across the two
screws in the switch body which at second thought are probably mounting
screws. I measured again from the wires extending from the switch after
removing them from the terminal block. I have no continuity when the
leaf/switch is in the open position; I have continuity when the leaf is
compressed. This is true whether the engine is running or not. So, I'd
conclude that the switch itself is working although I don't get the engine
stall. My wiring diagram says the white/green wire runs to a connection
on the distributor and the black wire runs to the starter slave solenoid.
I'm going to check those connections now.
