After it has sat for enough time that you don't expect it will charge, connect a test lead from the generator's "F" terminal to a GOOD ground.
Start it up. If it charges, suspect the VR.
If it does NOT charge, check the voltage at the "A" terminal. If it's less than about 8 Volts, the cutout (in the VR) cannot be expected to pull in.
If this is the case, suspect a short in the armature, or bad field coils, or field poleshoes that have been removed, and are not TIGHTLY fastened inside the generator's "belly", or have dirt, rust, or debris clamped between them and the generator's "belly".
