ALP 1 The starter does not work
NOTESTest the condition of the battery (see 80A, Battery, Test 1 Battery check).
Test the condition of the power fuse (see TEST 2 Test of power fuse condition and
source of fault).
Check ET010 Starting conditions met (see 87B, Passenger compartment
connection unit, Fault finding - Interpretation of statuses).
Check that the engine is not jammed.
Check that the following terminals are correctly
tightened:
the battery,
the starter,
the engine earth,
the bodywork earth.
Are the terminals correctly tightened?
Retighten the terminals (see MR 370,
Mechanical, 80A, Battery, Battery:
Removal - Refitting).
Check that the following wires are in good condition:
the wire connecting the battery +, component code
107, to terminal B+ of the starter, component
code 163,
the wire connecting the battery - to the bodywork
earth,
the wire connecting the engine to the bodywork
earth.
Are the wires in good condition?
Repair the damaged wires and terminals. If
the connection is faulty and there is a repair
procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring:
Precautions for repair), repair the wiring,
otherwise replace the wiring.
Try starting.
If the starter still does not turn, can a clicking noise be
heard when the starter is activated?

NOTESNone.
Check the condition of the battery terminals.
Confirm that there is no corrosion on the battery
terminals.
Check the tightness of the terminals (see MR
370, Mechanical, 80A, Battery, Battery:
Removal - Refitting).
Are the terminals and posts in good condition and
not corroded?Clean the terminals and posts or replace them, if
necessary
Check that there are no electrolyte leaks from the
battery (cracks or breakage).
Check that the mechanical mounting of the
battery is sound (see MR 370, Mechanical, 80A,
Battery, Battery: Removal - Refitting).
Is the battery in good condition?Change the battery and clean the surrounding
area on the vehicle if necessary.
(see MR 370, Mechanical, 80A, Battery,
Battery: Removal - Refitting).
Disable the engine injection (see 13B or 17B,
Interpretation of commands).
With the starter activated, measure the voltage
on connection BPDA between the + terminal of
the battery, component code 107, and the B + of
the starter, component code 163.
Is the voltage > 2 V?Repair the damaged wires and terminals. If the
connection is faulty and there is a repair
procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions
for repair), repair the wiring, otherwise replace it

With the engine running and the main beam
headlights and heated rear screen on, measure
the voltage between the battery B+, component
code 107, and the alternator B+, component
code 103.
Is the voltage > 0.7 V?Check that all the wires connecting the battery,
the alternator and the starter are secure and in
good condition, and that all their terminals are
correctly tightened and secure.
Repair the damaged wires and terminals. If the
connection is faulty and there is a repair
procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions
for repair), repair the wiring, otherwise replace it
With the engine running and the main beam
headlights and heated rear screen on, measure
the voltage between the negative terminal of the
battery, component code 107, and the alternator
frame, component code 103.
Is the voltage > 0.7 V?Check the earths of the engine, alternator,
chassis, gearbox, battery or starter (tightness,
condition of terminals, condition of wires).
Repair the damaged wires and terminals. If the
connection is faulty and there is a repair
procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions
for repair), repair the wiring, otherwise replace it
The electrical circuit is in good order.
