Yes, some makes/models of alternators will self excite, it probably depends on there being some residual magnetism left in the rotor.

Years ago I fitted a Lucas ACR series alternator to a `65 Mustang which had no warning light, but did have an ammeter.

The charging kicked in only when the engine was revved to about 2000 rpm but once it got going it would then keep charging right down to idling speed.
