The wiper motor (6v + ground) has three wires. Non of which are marked.

The switch has 4 posts. B (battery) F (field) A (armature) (I am assuming) And the 4th post is not marked.

How can I test/tell which wire goes where? Is there a way to measure which is field which is armature and which is ???

Thanks in advance,
