<p>A wiper motor (10) comprising an electric motor (12); an output gear (32) connected to, and rotatable by, the electric motor (12); a parking plate (30) secured to the output gear (32) for rotation therewith; three contact fingers (F1-F3), one (F2) of which makes a continuous sliding electrical connection (P2) with the parking plate (30), and the others (F1,F3) making alternating sliding electrical connection (P1,P3) with the parking plate (30), the said other contact fingers (F1,F3) being connectable across the poles of a power supply for the electric motor (12); and an electrical resistance (40) electrically connected between the said one contact finger and electrical ground. Provides reduced, or eliminates, radio interference noise associated with the parking plate (30) and its connections.</p> |
