Function Checks

Terminal No. 8 of control unit must be grounded for cruise control to operate. When brake pedal is depressed, brake switch closes and voltage to brake lights electrically interrupts ground circuit to control unit, cancelling operation. Power is supplied through fuse No. 5 (8 amp) to terminal No. 1 (control unit), terminal No. 2 (control switch) and terminal No. 1 (speed sensor).
