[QUOTE="Trikky2, post: 564167, member: 240"] The earth is needed so that when the wiper reaches the end of its sweep the motor is earthed out and stops through magnetic induction. If you remove the earth at park lead then the inertia of the motor will allow it to spin on until the segment picks up power again and it will re start the cycle. For intermittent control you will need to fit a similarly wired relay control. An ordinary simple wiper delay circuit will get shorted out by the earth brake system. [/QUOTE]
