The car generator is a mechanism that converts mechanical energy from the engine into electrical one. The generator is used to recharge the car battery. A good automobile generator must meet relatively high reliability requirements, since it ensures constant and proper function of many components of a modern car. The generator must also be resistant, lightweight and small sized and have a low noise level. To generate electricity, voltage must be submitted to the coil. This happens when you turn on the ignition switch. The amperage in the coil is coordinated by the voltage regulator. The generator rotor is driven by a V-belt through a pulley. The electromagnetic field, produced by an induction coil, induces alternating electrical amperage in the starter winding.

The voltage from the stator is rectified by the rectifying unit and made permanent. The rectified voltage goes then into the car`s on-board electric system. The generator operates in very unfavorable conditions. It is exposed to moisture, dirt, oil, which are even more harmful because of the high temperatures in the engine compartment. Even a short-term function of the generator disconnected from the battery should be avoided. The flash voltage that occurs when you disconnect the battery is very dangerous for all electronic systems and devices of your car. Nor can we allow the working capacity check of the generator on the "spark" through a short-time combination of pin terminals with the "mass" of the vehicle. In this case very high amperage goes through the rectifier unit, which will damage the power diodes.

Only a reliable and high quality electric generator can protect your vehicle from unexpected malfunctions and ensure the stable functioning of your vehicle. So if you want to buy a generator, go to our online store. And we guarantee not only lower prices, but also short delivery times. You can also order other car parts such as rear lights, fuel tank or springs.

What is necessary to know about automotive alternator replacement: lifetime limits, common defects and their signs, tips and recommendations

Lifetime limit of the car alternator is about 160 000 operational kilometres. This component can lose operability due to destruction of the pulley, thermal damage of the brushes or contact rings, breakdown of the voltage regulator, short circuit of the stator winding, destruction of the bearing, damaging of the diode bridge and wires.

Common signs that indicate necessity of component diagnostics are excessive or insufficient voltage in the car mains. The first can be detected by quick breakdown of electric equipment, the second can be signalised by a special dashboard indicator. Also, alternator defect can be indicated by battery overcharge, coming with electrolyte boiling, or its quick discharge, which is noticeable due to activation of a special dashboard indicator. Moreover, unusual sounds during engine operation, dim headlights, changing of their intensity at rpm increase are also causes for alternator inspection check.

Diagnostics of the automotive alternator defects is performed at a service station and consists of measuring voltage in the car mains or checking demounted component with the help of a special stand. Voltage measuring is performed at the battery terminals, then the engine starts and readings are checked with the engine  running. Deviation of the readings from allowable values indicates the necessity of alternator replacement.

Replacement of the alternator is performed in car service station conditions. This procedure requires usage of special tools and includes works with high-voltage wiring and demounting of corresponding components. Particularly, you will need to remove the engine guard, a wiring harness connector,  belt and alternator adjustment bracket. After this, demount the alternator and install a new one.
