start by testing the field coils. They should draw 2.0 amps. You need only the 6 volt battery 3 pieces of wire and a ampmeter to do the test. If the field coils test good, you'll need to pull the armature and take it to a old starter shop or electric motor repair shop in your area and have them test it for shorts,opens,grounds.
