[Healeys] Am I on track, or crazy:)

[Bob Spidell]

It's been years since I've had a cut-off switch apart, but I recall the 
internals being pretty robust (a couple large contactor plates). The way 
they could fail would be a build-up of corrosion, but that would likely 
occur over time and would probably affect starter cranking as well.

I'd suspect the condenser--if you have a points ignition system--or fuel 
delivery, new pump notwithstanding.
