The Rotating Lights:
The rotating headlamp assembly consists of dual headlights mounted in housings, the back of which are ornamentated to match the configuration of the grille. Mounted in the outside ends of the grille, the housings are rotated 180 degrees by electric motors when the headlight switch is turned on or off.An indicator light on the instrument panel stays lighted until the fully open position is attained. This safety feature warns the driver that one or both of the headlights are not fully opened and therefore not lighting the road properly.
turning the headlight switch off rotates the housings 180 degrees, turning the headlights off and concealing them in the grille. Should the operator desire to leave the headlights exposed but turned off, a separate toggle type switch in the instrument panel will override the system. The headlights can then be controlled in the same manner as conventional headlights.
Rotating Headlight Circuit
Opening:
Current flows to the control relay when the headlight switch is turned on keeping the contact points open. This interrupts current flow to the closing relay. Current then flows from the dimmer switch to the opening relay closing the contacts in the relay feeding the opening circuit to the motors. The motor rotates the housing until the housing stops contact the limit switches and interupt the ground circuit to the opening relay.Closing:
Turning the headlight switch off closes the control relay points, causing current to flow to the closing relay. The motors rotate the housings till the stops contact the limit switches which interrupt the ground circuit of the closing relay.Override Switch
When the headlight switch is turned on, the override switch breaks the ground circuit to the closing relay when placed in the override position. Should both headlights fail to open or close, continuity of the override switch should be tested first with an ohmmeter.Limit Switches
Four limit switches control the amount of travel of the headlight housings by interrupting the ground cicuit of the particular circuit in operation at the time. Adjustable stop screws located on the inner surfaces of the headlight housings provide a means of aligning the headlight housing with the center grille. With the headlight open, turn the stop adjusting screw clockwise to move top of housing out and counterclockwise to move housing in. The housing should be adjusted in the closed position in the same manner.
Relays:
Three relays are mounted on the far right side of the bulkhead in front and slightly below the glove box. The center relay is the control relay. The relay on the left is the closing relay and on the right is the opening relay. Both the opening and closing relays are identical in operation and are interchangeable. The control relay can be identified by the three terminals while the opening and closing relays have four terminals each.
