of this reading, the regulator should be re-
moved and taken to an authorized Auto-Lite
dealer for replacement.
NOTE: If car is out of warranty, remove the
cover and adjust the current regulator spring
hanger to the necessary 36 ampere output.
To prevent operation of the voltage regulator unit
while making this adjustment place a jumper across
the voltage regulator points. For final checking, the
regulator cover must be in place on regulator.
CAUTION: Momentarily touch the negative
battery cable to battery negative post to deter-
mine that there is no sparking between the
battery negative post and cable terminal, then
connect negative cable.
REGULATOR CONTACT POINTS
In normal use the contact points on all three
regulator units will become grayed. If the contacts are
burned, dirty, or rough, the points should be filed just
enough to secure a smooth surface. File parallel with
and lengthwise to the armature. Clean the points with
a piece of linen or lintless bond tape dipped in carbon
tetrachloride and follow with dry tape. Use clean tape
for each set of contacts.
DISTRIBUTOR
The distributor rotates in a clockwise direction. The
distributor shaft has an offset tongue end which fits
into a slot at the end of the oil pump shaft gear.
Incorporated in the distributor is an automatic
centrifugal advance and vacuum advance control.
The automatic centrifugal advance provides the
proper ignition timing in relation to engine speed. The
vacuum advance control provides additional spark
advance over the centrifugal advance through the
engine vacuum. When the engine is running under
light load and engine vacuum is high, the breaker
plate is rotated to the maximum advanced posi-
tions. However, under heavy load conditions, as
when the throttle is opened for additional accelera-
tion or hill climbing, the engine vacuum is low, the
breaker plate is rotated to the retarded position to
prevent detonation or pinging.
Correct spark setting is obtained when the
number one cylinder is at top dead center on com-
pression stroke, rotor facing No. 1 terminal of
distributor cap, distributor set in mid-position in
the quadrant, and contact points just opening.
BREAKER POINT ADJUSTMENT
Breaker points may be adjusted with distributor
installed in car as follows:
1. Remove distributor cap and rotor.
2. Crank engine until the fibre block on the contact
arm rest on the highest point of the cam lobe.
3. Loosen the contact support lock screw (B) Figure
6, and turn the eccentric adjusting screw (D) until
the correct gap is obtained. Distributor point gap is
.020".
4. Tighten contact support lock screw and recheck
point gap. If necessary bend stationary contact to
secure correct alignment.
