[Healeys] Testing cut-off switch/coil ground

[Freese, Ken]

He said he lost all power. To me that is not just the ignition. If the
black/white wire is grounded, you only lose ignition.
I think he has a battery terminal problem with the hot post, not the ground
post.

I'm betting on the switch as well, having had the same problem.
However, as a quick fix/test of the coil grounding circuit, the best place to
disconnect the black-white wire is in the bundle of front-to-rear connectors
under the fuse block. At the coil, the black-white is hard-connected with the
white wire from the dizzy(?) to a single connector, so to disconnect "at the
coil" you'd have to cut the wire.
When I fixed mine, it turned out that a tiny circlip on the cut-off switch
shaft had disintegrated, allowing the shaft to pull out just enough to ground
the coil to the chassis but while still allowing a connection between the
battery and chassis.
