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.
