lie ('adilhic-I)cloo starting and lighting system was developed as a
t of many years of effective cooperation between the Dayton Engineerlaboratories
Company and Cadillac engineers.
'lie units of the starting system include a source of current supply—a
rat or; a means of storing the current generated—a storage battery;
i melhod of applying the current to crank the engine—a motor.

L single wire system connects the different units, the circuit being eom-
'(1 through the frame. Connections from the chassis circuits to the body
lits are all made through accessible terminal blocks on the dash.

The generator is driven at 1½ engine speed by the crankshaft through
same .silent chain as the water pump and is located on the right side of
motor, directly back of the water pump. Current regulation is by an adible
third brush, and an automatic thermostatic switch. The switch
ices the charging rate when the engine and generator warm up.

The starting motor, a Cadillac-Delco six-pole unit, is mounted horizon-
.* at the right side of the transmission case. The starter pinion, which
lies with teeth on the outside of the flywheel, is controlled by the starter
ill. The starter has an exceptionally high stalling torque, capable of
iking the engine al any temperature.

.SWITCH
A locking cylinder on the instrument board which acts as an ignition
switch, is connected to the distributor by a hardened armored cable, impossible
to cut. The switch "grounds" the connection leading to the distributor
when the ignition is shut off. This device renders the car theft proof.

Two large headlamps, twelve inches diameter, of the bullet type are used.
These have a windsplit tapering from the front, top of the lamp to the apex a I
I lie rear and this windsplit is carried out also in the two side lamps on cowl
brackets.
The headlamps are mounted on brackets attached to the fenders, and a
horizontal monogram rod between the headlamps, and vertical nickeled
lamp standards add a striking note to the appearance of the car.
The headlamps have double filament bulbs, and highly efficient fluted
diffusing lenses which deflect and spread out the rays. They are controlled
by a switch at the center of the steering wheel. A single wire system supplies
current to the lamps, one side of each lamp socket being grounded.
The headlamps, side lamps and tail lam]) are controlled by a single lever
at the center of the steering wheel. This operates a switch located at the
bottom of the steering column. The instrument board lamps are controlled
by a separate switch on the instrument board.
The tail lamp is mounted on the left rear fender. The stop signal switch is
operated from the foot brakes, the lamp being placed on the right rear fender.
Protection is afforded to the various circuits by circuit breakers.
