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.
