THE FORD STARTING AND LIGHTING SYSTEM 57
and Ford 21 candle-power gas filled bulbs, when properly focused and aligned,
pass the lighting requirements of all states, and should they get out of focus
or alignment they should immediately be re-focused and re-aligned. Headlights
not equipped with the Ford refracting lens or the Ford 21 candle-power gas filled
bulbs will pass the lighting requirements of all states if these lenses and bulbs
are installed.
How is the Headlight Lens installed?
Remove the door by pressing in and turning to the left until the pins in the
door rim disengage from the notches in the lamp case. You can then readily see
how the lens fits into the door rim.
What about Bulb
replacement? Answer No. 128
When replacing burned out bulbs purchase genuine Ford bulbs (marked with the
name FORD on the glass), as satisfactory results cannot be obtained with the
many inferior bulbs now on the market. It is absolutely essential that the
Ford 21 candle-power gas filled bulbs be used in the lamps equipped with the,
Ford Refracting Lens as the use of any other than genuine Ford bulbs may result
in the lights failing to meet the lighting requirements of the various states.
Care should be exercised not to touch the reflector except with a soft clean
cloth.
How are the Headlights
focused? Answer No. 129
Place the empty car on a level surface facing a white wall or screen 25 feet
in front of the headlights. This wall must be shielded from direct light sufficiently
so that the light spots from the headlights can be clearly seen and should
be marked off with black lines as follows: One horizontal line 32 inches above
the surface on which the car is standing, and three vertical lines 14 inches
apart. The center line of the car should be directly in front of the center
vertical line. Turn on the bright lights, then focus by means of the screw
on the back of the lamp, adjusting to obtain an elongated elliptical spot of
light on the wall with its long axis horizontal. (See plate No. 24.) Adjust
the bulb to obtain as good contrast and as well defined cut-off across the
top of the spot of light as possible. With the lights thus focused for the "bright" filament,
the "dim" will be satisfactory.
How are Headlights aligned?
Headlamps may be aligned by bending the headlamp brackets so that the tops
of the bright spot on the wall or screen 25 feet in front of the car are
at a line 32 inches above the level surface on which the car stands and so
that the beam of light from each headlamp extends straight forward; that
is, with the centers of the elliptical spots of light 28 inches apart. (See
plate No. 25.) Owners may prefer to have their lamps focused and aligned
by an authorized Ford dealer as all Ford dealers are specially equipped to
do this work.
What about repairing Starter and Generator?
If either the starter or generator fails to give proper serivice, the owner
should at once consult an authorized Ford dealer. Owners should not attempt
to repair or adjust the mechanism of the starter and generator.
