Field coils are grounded with one wire coming outside the case to ground.
Field resistance is ~ 1 ohm
Armature was checked for opens: none, shorts: none, ground:, none.
Brushes are making full contact.
Diode cutout tests good, No output from generator at cutout input.
Marshall, third brush was set half way, at that setting generator output shows 0 volts, I'll try full down and see what happens.
