How to Bench Test Wiper Motor?
High is not correct way to describe what the Brown wire from A does.
edit. did a little reading.
The shunt field is in the motor means power is need to both the stator (fixed windings) and the armature (spinning windings) .
So bench testing the motor requires power to the16 gage brown wire and power to the 18 gage red wire, plus a ground.
