If it was made in the '40s, it could be a generator, not an alternator.  Take resistance
measurements and post them.  Read this manual:

   Very possible . . . if not probable. If it has
   been a long time since the generator was operating,
   it's likely to have lost residual field flux.

   It's likely that the four terminals are simply
   Armature+, Armature-, Field- and Field+
   (supply from regulator) . . . the jumpered
   terminals would be A- and F-.

   Does the ship's maintenance literature speak to
   a flashing procedure? Lacking a 'qualified'
   procedure, you can rig a current limited jumper
   (a 55W automotive headlamp is a cheap limiting
   resistor). While the engine is running and generator
   switch is ON, use your 'test lamp jumper' to connect
   from Bat to Arm on the regulator. This should
   put enough current into the generator system to
   cause it to excite it into self-sustained operation.

   After it comes up, turn on as many ship's
   loads as you can like lights, pitot heater, blowers,
   etc and bring engine rpm up to fast idle . . . the
   generator load meter should show some significant
   output.

   It only takes a minute or so to 'recharge' the field
   such that it should come on line normally the
   next time you fire it up.
