Check the condition of the battery terminals.
Check that there is no corrosion on the battery
terminals. Check that the terminals are
correctly tightened and secure (see MR 411
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 411, Mechanical,
80A, Battery, Battery: Removal - Refitting).
Change the battery and clean the surrounding
area on the vehicle if necessary.
(see MR 411, Mechanical, 80A, Battery,
Battery: Removal – Refitting). Is the battery in good condition?
Inhibit 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 107, and the B+ of the
starter, component 163.Repair the damaged wires and terminals. If the
connection is faulty and if there is a repair
procedure (see Technical Note 6015A,

procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring:
Precautions for repair), repair the wiring,
otherwise replace the wiring With the engine running and the main beam
headlights lit and the heated rear screen on,
measure the voltage between the B+ of the
battery, component 107, and the B+ of the
alternator, component 103.
Is the voltage > 0.7 V?
With the engine running and the main beam
headlights lit and the heated rear screen on,
measure the voltage between the negative
terminal of the battery, component 107, and
the alternator frame, component 103.Check the earths of the engine, the alternator,
the chassis, the gearbox, the battery, or the
starter (check the tightness and condition of
the terminals and the condition of the wires)
(see Technical Note for the relevant
vehicle).
Repair the damaged wires and terminals. If the
connection is faulty and if there is a repair
procedure (see Technical Note 6015A,
