ALP1 The starter does not work
NOTESTest the condition of the battery (see 80A, Battery).
Test the condition of the power fuse (see TEST 2).
Check that fuse F9 on component 1016 is in good condition.
Check that the engine is not jammed.
Check that the following terminals are
correctly tightened:
⇒ the battery
⇒ starter
⇒ engine earth
⇒ bodywork earth
Retighten the terminals (see MR 411, 80A,
Battery, Battery: Removal - Refitting).
Are the terminals correctly tightened?
Check that the following wires are in good
condition:
⇒ the wire connecting the battery +,
component 107, to terminal B+ of the
starter, component 163,
⇒ the wire connecting the battery - to
the bodywork earth,
⇒ the wire connecting the engine to
the bodywork earth.Repair the damaged wires and terminals. If the
connection is faulty and if there is a repair
procedure (see Technical Note 6015A, repairing
electrical wiring, wiring: Precautions for
repair), repair the wiring otherwise change the
wiring. Are the wires in good condition?
Try starting.
If the starter still does not turn, can a clicking
noise be heard when the starter is
activated?

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?
(i 1)
< 14.8V> 14.8V

TEST2 Test the condition of the power fuse and the cause of its fault
NOTESCheck that the engine is not locked
With the ignition off, measure the voltage between the negative
battery terminal and the power fuse output.
Is the voltage greater than or equal to 10V?
The power fuse is sound The power fuse is faulty
With the battery disconnected, measure the resistance between
the negative battery terminal and the power fuse output.
Is the resistance
≥ 10 Ohms?
Disconnect the alternator + terminal and
then measure the resistance between the
negative battery terminal and the power
fuse output.Possible external causes:
use of a "starter charger", excessively long
use of starter (e.g.: activate the starter, gear
engaged for driving the vehicle) etc.
Is the resistance
≥ 10 Ohms?

Check the wiring connecting the alternator and the
starter to the battery + terminal (see TEST 3).Replace the alternator (see MR 411, 16A,
Starting - Charging, Alternator: Removal -
Refitting).
Is it in good condition?
Replace the starter (see MR 411, 16A, Starting -
Charging, Starter: Removal - Refitting).
Repair the damaged wires and terminals. If the
connection is faulty and if there is a repair procedure
(see Technical Note 6015A, repairing electrical
wiring, wiring: Precautions for repair), repair the
wiring otherwise change the wiring.
Replace the power fuse (see MR 411, 80A, Battery, Battery: Removal - Refitting).
