REMOVAL
Remove the air filter (two mounting bolts at the
top, two mounting nuts at the bottom (1)).
Remove, from above, the two nuts fixing the ex-
haust downpipe to the manifold.
Slacken, without removing it, the nut on the
clamp connecting the downpipe to the exhaust
pipe.
Tilt the exhaust downpipe towards the gearbox.
Remove the nuts securing the manifolds:
- nuts (A) from above,
- nuts (B) from below.

To remove nut (C) located above the starter mo-
tor, use a small ratchet (6.35 mm square) and a
universal joint.

Alternator

OPTIMA 5800 Diagnostic station
CHECKING THE CHARGING CIRCUIT USING THE DIAGNOSTIC STATION
The OPTIMA 5800 diagnostic station allows the alternator to be checked by measuring the voltage and cur-
rent delivered , with or without electrical consumers .
NOTE : the Amps clamp used for this station is of the inductive type (measurement range: 0 to 1 000 A). It
is fitted without disconnecting the battery, which allows the the computer memory and adaptive informa-
tion to be saved.
Fit the Amps clamp directly at the alternator output, with the arrow pointing towards the alternator (any in-
correct positioning is detected by the station).
The measurement is carried out in three stages :
- measurement of the battery voltage, ignition off,
- measurement of the regulated voltage and of the current supplied, without consumers,
- measurement of the regulated voltage and current supplied, with a maximum number of consumers.
On completion of the test, the values noted will lead to the following fault finding messages :
- Battery voltage, no load < 12.3 V = battery uncharged.
Without consumers :
- Regulated voltage > 14,8 V = > regulator faulty ,
- (regulated voltage, no load < 13.2 V) or (charging current< 2 A) = >charging fault.
With consumers :
- Regulated voltage > 14.8 V = > regulator faulty,
- Regulated voltage < 12.7 V = > it is necessary to check the alternator supply in relation to its specifica-
tions :

PRINCIPLE
In the loop mode (see section 17 "Richness regulation"), richness regulation (# 35), corrects the injection ti-
ming to give fuel metering which is as close as possible to richness 1. The correction value is close to 128, with
limit values of 0 and 255.
Variations may affect the components of the injection system and the correction may drift towards 0 or 255,
to ensure richness 1 is obtained.
Adaptive correction allows the injection mapping to be adjusted to recentre the richness regulation to 128
and to ensure a constant authority of correction to make the mixture leaner or richer.
Adaptive correction to richness regulation has two parts:
- Adaptive correction for average and high engine loads (#30)
- Adaptive correction for idle speed and low engine loads (#31).
Adaptive corrections take 128 as the average value after initialisation (erasing the memory) and have the
following threshold values:
Adaptive correction only takes place when the engine is warm, in the loop phase (#35 variable) and for a
specified manifold pressure range.
The engine must have operated in the loop mode for several pressure zones in order that adaptive correc-
tion begins to change to compensate for the variations in engine operating richness.
Following reinitialisation of the computer (return to 128 for # 30 and # 31) a special road test must therefore
be carried out.
