Check for 12 V on relay 232 between
connection 1A of component 232 and a
chassis earth when starting is requested.
Is there 12 V?Replace the starter relay (see MR 411
Mechanical, 81C, FUSES, Engine
compartment fuse and relay box: List and
location of components).
Continuity and/or insulation fault on
connection 1A between components 232 and
163. If there is a repair method (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair) repair the
wiring, otherwise replace it.

TEST1 Alternator supply test
NOTESTest the condition of the battery (see 80A, Battery).
Measure the voltage at the battery terminals with the engine warm and running at idle speed for 2 minutes and with
all consumers switched off.
Voltage value?
Replace the alternator (see MR 411, 16A, Starting - Charging,
Alternator: Removal - Refitting).
Visually inspect the consequences (battery condition, corrosion, etc.).
With the engine at idle speed, connect a current clamp to the alternator B+ wire, connection BPDA, with all
consumers switched off.
Current < 5 ACurrent between 5 A
and 35 ACurrent > 35A
Replace the alternator
(see MR 411, 16A, Starting -
Charging, Alternator:
Removal - Refitting).Keep the engine speed at
3000 rpm and still with no
consumers switched on.Check that there are no
electrical components
consuming an abnormal
amount of current.
Disconnect the fuses one by
one to identify the consumer.
To be examined Value of measured current?
