Abstract:
A wiper system for a machine is provided. The wiper system includes a first motor configured to operate a first wiper and a second motor configured to operate a second wiper wherein the first motor and the second motor are connected in a parallel configuration. The wiper system further includes a power source which is in electrical connection with the first and the second motors for energizing each motor to move the respective wipers. The wiper system includes a switch configured to simultaneously operate the first motor and the second motor in one of a high speed mode, a low speed mode, or a park mode. The wiper system includes an isolating circuit configured to isolate the first motor from the power source and allow the second motor to run independent of the first motor when the switch is set in the park mode and speed of the first motor is different from speed of the second motor.
