So, if the alternator warning light comes on, and then goes out when the alternator starts charging, I can pretty much guarantee the ignition switch is NOT preventing the alternator from charging.
The ignition switch *might* be causing a current draw which drains the battery faster than the alternator can charge it, but probably not unless the draw is from the starter running continuously. They already said the alternator would fix it and proved themselves wrong a few hundred dollars later, I'd get it running, unplug the glow plug harness or remove the strip fuse from the glow plug relay and get it home.
