Diagnosis of the battery, alternator, starter motor auto electricians

Before the onset of winter to the starter and the generator by using a cold start is reinforced load. Why is breaking the starter and generator (most common), and where they need to be addressed? This publication tells how to make a diagnosis of the battery, alternator, starter motor auto electricians. Additionally, it should be recalled that the car used 2 types of power source. On the one hand - a generator that produces the conversion of mechanical energy into electrical engine, and produces a power of consumers, when the engine is running. On the other - the battery, which converts the stored chemical energy into electrical energy when the engine is not running. The bulk of the problems happening in the auto - electrical engineering, namely the loss of contacts, which can destroy the fuses, oxidize or cause overheating of contacts, melting wires short-circuiting. The complex, which provides power to all elements of the car includes: battery, starter, ignition system (used on engines with a carburetor), the injection system (for injection engines). This also applies: control system, display system, alarms, system responsible for lighting, air conditioning, navigation system, sound system and much more. Look at three key positions - starter, alternator and battery. If their work is not stable, then all the elements included in the electrical system is not able to function. There are two types of problems associated with the sale - an electrician. For example, alarm malfunction, that is, flash output node failure. This includes the closure of a starter, going on between turns, hit the generator into the water. There is still failure associated with wear (bearings, shafts, anchors, etc.). If we examine the reasons for which the overwhelming number of failures in the electrical system, it should be noted that at low temperature (winter) to the starter operates a large load, and in summer, on the contrary. If it turns out that if the starter or the details of his site has wear, when it will pass through the current, it can fail. The same applies to the generator, which operates a big load in the winter. Therefore, before the onset of winter to perform diagnosis of the ignition system, as well as cars - electricians. Starter Starter is called a powerful electric motor, causing the flywheel to spin, and, consequently, lead to the rotation, and crankshaft and the engine included in the piston group (the main condition for starting). In modern vehicles includes starter gear type with permanent magnets. For starters, electromechanical damage may include: a broken mask starter (the result of poor installation), damage Bendix (occurs when wearing the crown of a flywheel, re-enables the starter when the engine is running, fuel is of poor quality, incorrect configuration of the injection pump, and many others); blue collector armature armature of the Bendix, and when fused plastic parts of the planetary gear (in case of overheating, the starter rotates the engine, the ride takes place on the starter, defective ignition); faded anchor (brush wear, misused launchers); overheating and jamming overrunning clutch Bendix ( when the starter spins the engine) failure of anchor with planetary gear (starter rotates the engine). The most common injuries are broken starter holder with brushes (because of some mechanical damage of burns brush holder). This problem arises for several reasons - Brush wear, corrosion, burn holders come unsoldered brushes, hard running machine (brushes in their composition containing copper and graphite, and so in cold weather is their gradual blurring, and further failure). These faults are eliminated by replacing the brush holder and brushes themselves. Generators, in Latin, means the manufacturer. This is the most active component loaded car - electricians. When driving the generator shaft rotates at a frequency of 10 to 14 revolutions per minute, that is, if we take all the nodes in the car, the speed of rotation of the shaft will be very large (even greater than the frequency of revolutions of the engine). For the significant amount of time the generator design has undergone an impressive change. It is no longer used DC generators with vibrating voltage regulators. Many generators have made improvement: increased power output, reduced size and weight, have established robust security features. Has also been increased value of the maximum output current of 45 - 60 amperes to 90 - 140 amps, and more. This led to the emergence of devices that bring additional comfort in the car, use of modern technologies in lighting and heating the car. But even these improvements do not protect the generators from wear and tear. How to diagnose that the alternator is faulty? The battery is not charging the battery - the engine running and lights on the dashboard warning lamp. From this it follows that in the chain, the generator exciting, came out of the fuse; belt is weakened or broken, torn wire, or it is shorted, the voltage regulator is damaged when exploitation occurs recharge batteries battery. From this it follows that the fault can be a voltage regulator or, in some models of voltage regulators may be missing an extra "+" If the generator is very noisy, so could weaken the nut, fastened the pulley, and here can be attributed fault on the rectifier unit may be contaminated slip rings and brushes, the bearings are not lubricated or are worn out already, have torn the stator windings. It should be noted the most important thing. If a faulty generator - simple replacement of the battery to nothing lead. If the starter motor with a generator malfunction, you should contact the Service Center. In order for your starter for a long time functioned, you must follow the following tips: The starter should be included no more than 10 seconds. If you do not start the engine is a 30-second break, recommended tracking reliability of contacts at the battery terminals. In the case of oxidation of the terminals or the tip of the wires, it may be concluded that the starter is not received desired power, and as a result do not develop enough speed and torque; After starting the engine starter to shut down. If there is delay in the 2-3 seconds, then it will lead to rapid deterioration; If you do not have the necessary experience and knowledge, it is not necessary to repair the starter on its own. Best to seek professional help.
