• Increases the speed by 50 times

• Reduces the speed and multiplies the torque by 50 times

• Decreases both speed and torque

• Multiplies the speed by 50 times

What is the function of the electronic circuit within the wiper system?

• It increases the power to the motor

• It senses when the wipers are in their down position and cuts power to the motor

• It controls the speed of the wipers only
