4. Adjust the alternator belt tension appropriately. After driving a certain mileage, adjust the alternator belt tension appropriately, and tighten the calibration screws as needed. The alternator mounting bolts should be kept at a certain tightness.
5. Pay attention to the wear of the bearings. If insufficient lubrication is found, drip a few drops of engine oil into the oil cup. Be careful not to let it seep into the rectifier, otherwise it will affect the power transmission efficiency.
6. For scale buildup in the rectifier, polish it with fine sandpaper.
7. If the brush contact surface is uneven, smooth it with fine sandpaper. Replace brushes if the spring elasticity is insufficient or the brushes are excessively worn. If the brushes are too short but not damaged, insert shims into the bracket to ensure a tight seal with the rectifier.
8. If the brush bracket insulator is damaged, replace it with a new one.
9. If the alternator terminals are loose, tighten them immediately. If the insulation is poor, disassemble and repair it. 7. Use battery power: If the generator breaks down mid-journey but the destination is not far away, disconnect the wire connecting the voltage regulator to the field coil. If it is a three-brush generator, remove the third brush to stop the generator from generating electricity. Use battery power, and conserve electricity as much as possible.
10. Ensure the dust seals on the generator are secure; do not remove them to prevent dust from entering and causing mechanical failure.
11. Clean all wires regularly and keep them dry to prevent leakage.
12. Remove accumulated dirt and dust from the generator’s exterior.
