First understand I am NOT very good with a multi-meter. That is, I do a lot of touching this and that, not really knowing if I'm in the right spot(s).
when the key is in accessory position and/or the car is running, with wiper switch "ON" I can hear the motor "clicking" (doesn't really sound like arcing).
when I touch the left (from the front) connection on the motor, the meter reads 11volts
when I touch the right " " the meter reads 0 volts.
