2.16.9 Electrical Equipment Use
The electrical systems of the 40XT and 50XT Series Tractors use a 12V double wire system with a negative ground.
2.16.9.1 Battery
The battery is used to store the electrical energy produced by the alternator. The battery can then supply electrical
power to the electrical equipment on the tractor when the alternator is not turning or is running at low speed. It can
also help with the power supply when the alternator is overloaded for a brief period.
Frequently remove the dust and mud on the battery shell to avoid electric leakage. Check whether there are any
cracks in the battery case and/or leakage of electrolytes. Ensure good contact between the terminals and the
battery cables. The air vent on the plastic cover should not be blocked in order to avoid an explosion.
Frequently check the battery voltage. Charge it when the voltage is low.
The starter cranking time should not exceed 5 seconds each time to avoid excessive discharging.
If the tractor is not used for a long time, the battery should be removed for charging and maintenance.
2.16.9.2 Alternator
The alternator must be used with a matching regulator.
The silicon rectification alternator is minus ―—‖ grounded. The connection of the positive and negative poles of
the alternator, the regulator and the battery must be correct to avoid burnout of the alternator and the regulator.
Do not strike sparks to determine whether the alternator is generating electricity.
Remove the key from the ignition switch when the tractor is stopped to cut off the connection between the motor
and the battery and prevent the battery from discharging over an extended period of time.
2.16.9.3 Starter
The starter should not run for an extended period. The starting time should not exceed 5 seconds each time to
avoid damage to the starter.
If a grinding sound (teeth colliding) between the small gear on the starter and the flywheel ring gear is heard
when starting, turn the key back to its original position immediately and try again.
If the starter continues running after the key is back to its original position, shut down the engine immediately and
start again after the fault is remedied.
