2.11.7.5 Start Motor Noise Diagnostic

Before  the  diagnostic,  please  refer  to  the

2.11.2.1

 

Battery  Description  and  Operation

, 

2.11.2.2

 

Starting  System  Description  and

Operation

 and 

2.11.2.3

 

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

Go to step 4

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

2.11.8.4

 

Starter Replacement

Engine

Starting / Charging System JL4G18-D

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

2.11.8.4

 

Starter Replacement

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 

2.2.7.3

 

Intermittent

Fault Check

Yes

Step 2

Measure the battery terminal voltage with a multimeter, is it between 11 V and 14.9 V?

No

Go to step 5

Yes

Step 3

Check the charging indicator control circuit.
