I had a recent alternator charging problem: it was charging because of residual magnetism in the core, but suddenly stopped charging when the core degaussed sufficiently. It turns out that on at least some cars (possibly not datsuns) the alternator charge light on the dash actually controls the field voltage on the alternator, and if the light's not connected (or burnt out) the alternator will work for a while, but possibly not indefinitely.

It's the same with Datsun alternators. The "field" of the alternator is connected to the dash light. If the light is burned out, it won't charge.
Late on they added a resistor in parallel with the dash bulb, so even if the light burns out it will still initiate charging.
