IML: Re:window motor testing

["mike and linda sutton" <mikanlin62@xxxxxxxxxxx>]

Careful about taking the 12 source to the wires from the motor, they do NOT 
always just reverse the polarity of the two wires that pigtail out of the 
motor to change direction.  Quite often the case of the motor is used for 
the ground and one of the pigtail wires is for one direction and the other 
wire is for the opposite direction. IF the car in question has motors that 
are wired the same way my 62 is,  that will be how the motor works 
electrically.  To check these motors out, I make sure the motor case is 
grounded, usually by running a wire from one of the thru bolts in the motor 
case to a good ground - or the ground side of a test battery  in this 
instance.  Then I take the positive wire and touch it to one of the pigtail 
wires and then to the other.
