4.11.2 Battery Maintenance
Normally the maintenance-free battery does not require any special maintenance. Water does not have to be
added to maintain the level of electrolyte since the battery is sealed. You can observe the power levels from the
view hole in the battery: Green = full power; Grey = lack of power; Dark = no power.
As part of the tractor’s electrical system the battery requires some system level maintenance.
1.
Check the status of the battery. Make sure the case is not cracked or leaking, and the battery is secured
in place.
2.
The battery should be charged under the following conditions:
The engine is slow to start and/or the lights are faint.
The inspection hole becomes grey. It should be replaced when the inspection hole becomes dark.
The battery is under voltage. Measure the terminal voltage when discharging. There is a problem with
a 12V battery if the output voltage is lower than 10.5V.
3.
When being stored, the battery should be charged monthly. The charging method is as follows: charge the
battery by 0.1C20A (C20 is power capacity for 20hrs.). When the terminal voltage for the 12V battery
reaches 14.4±0.05V, you can continue charging for another 5hrs.
The tractor electrical system uses a 12V, single-wire, negative ground system. The system consists of the engine
starting equipment, lights, instruments, and signal devices.
The engine starting equipment includes the starter, alternator, battery, voltage regulator, and ignition switch.
For the operation and maintenance of this equipment, refer to the diesel engine instruction manual.
The lighting and signal devices include the headlights, rear lights (with top rear lamp for cab), turn signals, and
taillight set (turn signals, position and brake lights), combined instruments, speakers and fuses, etc.
The fans and controls for the cab HVAC system and the air conditioner compressor are also electrical.
