3. Fuel pump feed ( with engine running ) : ( DIAGRAM 3 )
- Disconnect the E.C.U.
- Disconnect from the air-flow sensor the air hose to the butterfly housing
- Switch on the ignition:
- Actuate the air-flow sensor flap by hand’ when the petrol pump contact closes the pump should be heard
working.
If not, test the circuit using a
battery operated ohmmeter, without forgetting to test between terminal G 36 ))
on the air-flow sensor and terminal H 20 .)) on the E.C.U. for continuity ( The 2nd terminal is not connected
to the E.C.U. ).
- The resistance between terminals (( 86 b H and G 85 )) on the relay box f //j/nor thc~ I~./I. h<~ntllnr~tp ) must be
between 52 and 78 12.

- Disconnect the E.C.U.

? - Check that the supplementary air control is properly connected ( arrow on the casing )~
In
If it is fitted the wrong way round. the port may be blocked.
- The resistance between terminals (( 34 1, and (( 48 )) on the- supplementary air control must be 50 Q approx-
- Visual checking the port on the supplementary air control must be open when the engine is cold, and closed
when the engine temperature is above 60” C
- With the engine cold. if the air pipe to the supplementary air control is flattened the engine rpm must decrease.
With the engine warm, if the air pipe is disconnected, the engine must accelerate.

- Disconnect the E.C.U.
- Using a battery operated ohmmeter, check there is no resistance between terminals (( 3 H and (( 18 )) of the
multiple connector board, with the accelerator pedal fully depressed

2 - Visually check the condition of the terminals ( male connectors on the E-C U., and female connectors
on the multiple connector socket ).
- With the engine running, tap lightly on the E.C.U., to detect any possible defect in the soldering ( dry
joints ).

1. Checking the condition of the contacts :
Check the voltage drop across the contacts ( contacts closed ) under a voltage of 12 volts. using a test-bench.
The voltage drop should be 0.2 volts max.
I
2. Checking the centrifugal advance curve :
a) Note the advance in stages for steadily increasing engine speeds from 0 to 3000 rpm. and for steadily
decreasing engine speeds from 3000 rpm to 0, t~/~kjj/$ SII~L’
the irirwasc, or d~,rrc~as~’ is c-o~~ti~ootl.5.
These points must fall within the shaded area of the curve.
b) To a certain extent. it is possible to correct the advance curve, by altering the tension of the springs for
the centrifugal weights To obtain this condition, slightly bend (
iv t/1(, np1)ro/)riotc, ciirectioll J the securing
brackets for the springs, or replace them.
IY NOTE : If luminous spots are produced outside the four normal positions at speeds under 3000 rpm. make
5 sure the contact points are clean and if necessary make sure the test-bench battery is fully charged. before
U replacing the contact-breaker unit. the spring of which may have weakened.

Run the distributor at a steady speed, and check that the dwell angle is equal ;o 55’ ? 2”30’. If this is not the
case, adjust the contact breaker to obtain this condition.
5. Checking the ignition condenser :
With the contact points open. measure the capacity of the condenser; This value must be 0.30 i 0.03 wF.
If this is not the case. replace the condenser.
6. Check the vacuum advance curve :
This check is carried out at a constant rpm of 200, with no centrifugal advance.
Check the points of the increasing curve. and the decreasing curve. If the vacuum capsule has n hathcr.
it will be necessary to blank it off during this check.
