Starting module
Precautions
The alternator of the machine is strictly prohibited to power the electrical equipments on the machine
separately in the absence of battery.
Metal tools or other metal conductors shall be kept away from the "B +" (Battery Positive) terminal and
"Ground" terminal of generator during operating the diesel engine. In order to avoid short-circuit. Short
circuit on the engine will lead serious results.
Troubleshooting procedures of alternator
Differing from the introduced fault detection methods for other components, the alternator fault detection
is implemented on the entire machine, which shall not be removed for individual inspection.
The following detection steps are inapplicable to the cases where the battery is fully charged and the ter-
minal voltage reaches 25V or above.
1. Turn the digital multimeter to 200V of voltage position.
2. Turn on disconnect switch of the machine, do not start the diesel engine, put red probe of a digital
multimeter over "B+" end of an alternator, put black probe over "Ground" terminal of the alternator,
and write down displayed value of the digital multimeter. The normal value is about 24-25 V.
3. Start diesel engine, step on accelerator, follow the measuring method described in step 2, and note
down the value on DMM again. Such value shall be higher than the measured value in step 2,
whereby, the alternator is in normal condition.
The above test procedures shall be implemented on unloaded machine (unload: the condition that the
electric lock is switched on, yet all the electrical switches or components on the machine are switched
off).
If the value on DMM is unchanged through the tests in steps 2 and 3, switch off the electric lock to
inspect the alternator as per the following steps.
1. Inspect the transmission belt of alternator in accordance with the methods introduced in the specifi-
cation. Readjust if it is too loose.
2. Check the security of alternator terminal, and fasten it with a wrench if necessary.
If the above-mentioned methods fail to solve the problem, please contact maintenance service sites of
LiuGong and Perkins.
