Re: [FWDLK] Autopark for Windshield wipers

[Ray Jones <hurst300@xxxxxxxxxxxx>]

The way these work is like this:
The motor has constant power. Inside the motor there is a pickup arm 
that revolves with the shaft. It provides the power to the motor. There 
is one segment of this contact ring which is separate and is not 
powered. When you turn on the switch you power this segment and the 
motor starts to run. As the pick-up arm wipes around the contact 
surface it is fully powered even as it goes over this segment. When you 
turn off the switch, you cut the power to this segment and when the 
motor revolves around to it, the motor stops since there is no power 
there.

There are, of course, variations of this set-up. Your problem may be 
that you have no constant power to the motor and it's only getting 
power from the switch, or the internal power contacts are bad, and the 
dead segment is getting power from the adjacent ones.
