ALP 2 The starter turns but does not engage
NOTESSpecial notes:
Disconnect the battery earth before handling.
Remove the starter (see MR 370, Mechanical, 16A, Starting - Charging, Starter: Removal - Refitting).
Check that the ring gear of the flywheel is in good condition.
Are the ring gear teeth damaged?
Replace the flywheel (see MR 370, Mechanical,
Engine and peripherals, Engine and cylinder
block assembly).
Check the condition of the starter (broken teeth or
worn gears).
Is the starter in good condition?
Replace the starter (see MR 370,
Mechanical, 16A, Starting - Charging,
Starter: Removal - Refitting).
Refit the starter (see MR 370, Mechanical, 16A,
Starting - Charging, Starter: Removal - Refitting).

TEST 2 Test the condition of the power fuse and the cause of its fault
NOTESCheck that the engine is not blocked.
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 correct 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 ΩΩ Ω Ω
?
Disconnect the alternator + terminal, then measure
the resistance between the negative battery terminal
and the power fuse outputPossible external causes:
use of a "starter charger", excessively long use of
starter (e.g.: activating the starter with the gear
engaged to move the vehicle) etc.
Is the resistance
≥ 10 Ω?
Replace the alternator (see MR 370, Mechanical, 16A, Starting - Charging,
Alternator: Removal - Refitting).
Check the wiring connecting the alternator and the
starter to the battery + terminal (see TEST 3 Wiring
check).
