regulation with the adjusting rod to meet the above requirements.
IX. Electrical system
The electrical system is composed of silicon rectification generator, regulator, starter (matching with
diesel engine), battery, lighting system, oil circuit pressure, oil temperature and cleanliness monitoring
systems, low pressure alarm and instruments.
The rated voltage of the system is 24 V, with negative grounding and single-wire system. The wiring
diagram is shown in Fig. 3-26.
Two 6-Q-195 batteries or maintenance-free batteries (Bolder 6-QW-120) are connected in series to
supply power for motor starting. During normal working, the generator charges the battery. In case of
failed or abnormal battery charge for some reason, remove the battery from the vehicle for charge.
(For details, see Use and Maintenance of the Supporting Battery in the Loader and Related Notes and
Flow Diagram of Battery Fault Judgment).
The battery charge shall be carried out as specified. Check the level of the battery every 5~7 days in
summer while 10~15 days in winter, and the level shall be 10~15mm higher than the electrode plate in
normal conditions; check if the electrode plate is sulfurized (featuring many white lead sulphate layers
on the top of the electrode plate), and the sulfurized battery shall not be used further, so special charge
way is required.
If the vehicle is to be stopped for a long time, charge the battery every month. After working, always
turn off the master switch of power supply to prevent leakage.

Notices:
1.
The electric lock on the instrument panel shall be turned on before starting and turned off after
engine stop;
2.
After normal engine starting, do not turn off the master switch of power supply randomly to avoid
generator operation under no-load condition which will cause sudden voltage rise and consequently
burn out the electric equipment;
3.
Turning off the electric lock and master switch of power supply under any of the following
situations can prevent accidents:
(1) Loss of control caused by large current due to starter motor contact adhesion;
(2) Circuit grounding caused during repair;
(3) Short circuit or grounding of electric equipment.
