It's very possible that a light bulb took out an alternator if that was its only path to ground. Virtually zero resistance followed by virtually infinite current followed by an electrical open almost immediately. A lamp is essentially the same thing as a short.

I measured the same voltage on the "L" exciter wire as the voltage at the battery, and the only warning light illuminating when I turn the ignition to "on" is the "Fasten Belts" light. So I took the ignition-on 12V source from the HEI plug and added a 470 ohm resistor, 1/2 watt, so when the battery voltage read 11.85 the L wire now reads 11.75. I've read stock CS alternator wiring has a resistor in the wiring in case the warning light goes out... my '80 probably does not have this resistor. A 50 cent bulb took out the alternator?
