The 122 does not have an alternator, it has a generator. They are apples and oranges as far as electricity goes.
They both require a voltage regulator, but the generator equipped 122 has an external voltage regulator which uses voltage from the battery to energize it.
With a completely dead battery (or no battery), once you remove the jumper cables, the voltage regulator de-energizes and the voltage produced by the generator does not reach the rest of the system to give ignition to the engine.
Hope that makes sense.
