2.11.7.5 Start Motor Noise Diagnostic
Before the diagnostic, please refer to the
Battery Description and Operation
,
Starting System Description and
Charging System Description and Operation
and perform the necessary checks.
Step 1
Start the engine, while monitoring whether the generator motor starts turning.
When the engine started and the starter remained at the bonding
position, whether there is loud "breathing" (If the starter remains in
bonding position and further increase the engine speed, the sound
may sound as an alarm)?
Yes
Check the flywheel ring gear for existence of
the following: tooth cracking, tooth loss, tooth
wear, flywheel bent or the tooth damage, if
necessary, replace the flywheel.
No
Step 2
When the engine started, and the starter gradually stops, is there any "rumble", "roar" or in some cases
"percussion sound "?
Yes
No
Step 3
The engine crankshaft rotates and the starts as per normal, is there any high-frequency hum sound?
Yes
Replace the starter motor. Refer to
Engine
Starting / Charging System JL4G18-D
2-565
No
Step 4
Remove the starter motor.
Check starter motor sleeve and clutch gear for clutch gear
cracks,worn or sleeve worn?
Yes
Replace the starter motor. Refer to
No
Step 5
Replace the flywheel.
Next
Step 6
Diagnostic completed.
2.11.7.6 Charging Indicator Always On
Step 1
Start the engine, is the battery charging indicator still on?
No
Intermittent Fault. Refer to
Yes
Step 2
Measure the battery terminal voltage with a multimeter, is it between 11 V and 14.9 V?
No
Yes
Step 3
Check the charging indicator control circuit.
