Abstract: The specification discloses a vehicle electrical control system capable of switching the alternator output between a uniform standard voltage and a uniform higher voltage. The control system includes a supplemental voltage regulator and a switching circuit for selectively switching the supplemental regulator into the system to regulate the conventional voltage regulator. Preferably, the control system further includes a timing circuit for powering a plurality of electrically heated windows in a timed sequence.

Abstract: A drive unit for a golf cart having a motor and a pinion mounted on a drive shaft extending from the motor. The motor is pivotally mounted on a leg of the cart and is adjustable to a number of positions including one where the pinion engages a wheel on the cart to drive the cart and another where the motor does not interfere with folding of the cart. A battery is suspended from the cart to power the motor, and a thumb switch is included to selectively activate the motor. Biasing structure is included to improve engagement of the pinion against the wheel when the motor is in its driving position.

Abstract: A rotary program switch is disclosed including a housing supporting a commutator for rotation. The commutator includes a plurality of axially spaced contact tracks, and a corresponding plurality of brush elements are supported in the housing for engagement with the tracks in response to rotation of the commutator. Certain of the brushes are mounted on a rotatable gear for selectively positioning the brushes relative to the housing from outside the housing, and the latter brushes are adjustably mounted on the gear. Others of the brushes are carried by a support arm reversibly mountable within the housing to selectively position the brushes in generally diametrically opposed locations in the housing. The support arm, in either position, is adjustable relative to the housing. The several adjustments enable performance of a desired switching program in response to rotation of the commutator in opposite directions relative to the housing.
