If in this case the electro-valve is not energized.
ensure ( using a test lamp ) that the winding in
relay ( 2) is not enerqized for an engine speed
below ”

If not. replace the electronic unit (3) after
having checked the connections.
2. Pneumatic components :
Ensure that the vacuum reaches capsule ( 4 1 ( device

Make sure the vacuum exists at the carburettor
outlet. If it does. and yet does not reach cap-

PETROL PUMP
AC DELCO pump reference E/PE 4.777
Auto-regulating diaphragm lift and force pump
operated by eccentric on camshaft.
This pump is fitted with (I device which enables it
to function on re-cycled petrol. This re-cycling is
effected by means of a by-pass .( 1 ) fitted on the
carburettor cover.
Excess petrol supplied by the pump returns to the
tank across an orifice calibrated from 0.8 to 0.9mm
in the by-pass union (1).

IMPORTANT NOTE
When the steering has been set in I( straight line >) position, (the marks in line with zero
on the sectors of the turntables
1 steering wheel and front wheels must not be touched throughout the whole of
the testing operation.
2. Check readings Ll and L2 ( see chapter I ).
3. Adjust the length of the telescopic rods approximately according to the front track of the vehicle, both rods
being of the some length.
IMPORTANT : Place the rods on either side of front axle so that they are parallel to each other and perpendicular
to the longitudinal axis of the vehicle and the overall
distance between them is exactly 2.48 meters.
The rods need not necessarily be at equal distance from the axle but the spacing between them is essential.
4.
To make the test :
Pivot one of the two projectors towards the front rod hnd read off on the graduated rule thr value indicated by the
luminous mark. Then pivot projector towards the rear rod and move this laterally until the snne reading is obtained
as for the front rod.
Repeat this operation with the other projector, pivotting it successively towards the rear rod and then towards
the front
rod and each time note the readings indicated by the luminous mark.
The reading shown on the rem alignment rod should be 1 to 4 graduations greater than the reading shown on the
front alignment rod which corresponds to a
toe-in between 1 to 4 mm.
NOTE Never adjust the lens between the two front and rear readings.
