The structures of 28V and 14V automobile generators are the same, and the maintenance methods are the same. The 28 volt generator is used on 24 V battery vehicles, and the 14 V is used on 12 V battery vehicles.
The automobile generator is an important component of automobile electrical appliances. Its functions consist of two parts: meeting the needs of various power-consuming parts and charging the battery. In order to keep the generator in a stable power generating state while the car is driving, the following maintenance work should be carried out regularly.
1. Once the car has covered some mileage, adjust the generator belt tightness appropriately and reattach the calibration screws if necessary. The generator tripod screws must maintain a certain tightness.
2. Pay attention to the degree of wear of the bearings. If a lubriInsufficient filling is noted, drip a few drops of engine oil from the mouth of the oil cup. otherwise it will affect the power transmission effect.
3. If the straightener is dirty, it can be polished with a fine emery cloth.
4. If the contact surface of the brush is uneven, you can smooth it with a fine emery cloth. When the spring elasticity is insufficient and the brush is excessively worn, new parts must be replaced. If the brush is too short and is not damaged, a gasket can be inserted into the holder to bring it closer to the rectifier.
5. The brush holder insulation is damaged and new parts must be purchased.
6. If the generator poles are loose, they must be tightened immediately. If the insulation is poor, they must be removed and repaired.
7. When the generator breaks down halfway and is not too far from the destination, theWires connecting the voltage regulator to the magnetic field coil can be removed. If it is a three brush generator, the third brush. must be removed so that the generator does not produce electricity. Use battery power for power supply and save as much electricity as possible at that time.
8. The dust ring on the generator must be firm and must not be removed and left unused to prevent dust from entering inside and causing mechanical failure.
9. Clean each wire frequently and keep it dry to prevent leakage.
Your problem may be caused by a low battery or high-power electrical equipment. When the car first starts, the battery power is insufficient and requires a large current from the alternator to charge, so the alternator is very hot. Check again after the cardrove for a while. If the temperature drops, the problem will not be serious, but high-power electrical equipment should be disposed of first.
