Well Bob,
Thanks! After a nice day out in heat/humidity staining the fence I decided to see what the delay circuit would do when connected to the wiper motor...and I'm confused as to the park circuit. It (the P connection) has 12v + when the ignition is on and also when the motor is running at high or low speed. I was thinking the relay sending 12v+ to the low speed winding would be sufficient, however the wiper motor moves only a bit at a time and doesn't park. Yet when the switch is flicked rapidly to low speed and back to off, the wiper motor makes a full sweep and parks. Ideas? A pulse stretcher?
