Hi Roman,
You're right, I took it apart, and it is a simple wiper system.
I then spent time figuring out how the wiper system works,
I can drive a wire high on one pin and then look for the other wire
to go high on another pin, to figure out positioning.
I just was not familiar with this type of system.
Live and learn.
Thanks,
Kevin
