The lifespan of an automobile generator is generally around 15 years. Most engines on the road today are designed to have a lifespan of more than 200,000 to 300,000 kilometers, but they operate with regular maintenance and little regard for cost. can reach 500,000 kilometers above.
However, there is no precise figure for the lifespan of a car engine. The lifespan of automobile parts, including engine life, now depends on many different factors, due to advancements in technology; , generators on cars are generally all maintenance-free generators. They only work when turned on, just replace them with new ones.
Detailed information
The car generator is the main source of power for the car. The following points should be taken into account daily:
Indetailed informationThe car generator is the main source of power for the car. p>1. Clean Frequently To remove dirt and dust from the exterior of the generator, keep it clean and well ventilated.
2. Frequently check the tightness of the generator-related fasteners and tighten the screws in time.
3. When installing the battery, be careful not to install it incorrectly. Usually, install the positive wire first and not the ground wire, otherwise the diode will burn out easily.
4. When using an integrated circuit regulator, the ignition switch should be turned off immediately when the engine is not running.
5. It is never allowed to use the “scratching” method to test whether electricity should be produced.
6. When the generator fails to generate electricity, it must be eliminated in time, otherwise it will cause a more serious breakdown.
There are usually 3 or 4 terminals on the alternator, which are marked with "十" (or armature), F (or magnetic field), "一" (or ground). ), N.. (or neutral point).
Directly identify the terminal with the thicker diameter as the “+” terminal; In order to identify the remaining three terminals, you can use the battery power cord to scratch them separately. The one with the strongest spark is terminal "1"; the one with the weak spark is the "F" terminal; the one without spark is the "N" terminal.
Use a multimeter to measure. . Set the multimeter to the Rxl position and perform two tests. Use the test rod to measure the resistance between each terminal and the chassis respectively, then exchange the test rods for measurement
If the resistance is zero. the two measurements are “one” limit; if they are both 5 to 6SZ (12V alternator) or 19.5 to 21St (24V alternator), it is the "terminal F" when the resistanceis 40 to 50St at a time; and ion at the other moment, it is the terminal “one”; when the resistance is 8 ions one time and 10 kf the other time, it is the “N” terminal.
Detailed information:
Terminal E is the grounding terminal of the generator. negative pole of the generator.
Terminal F is the power terminal of the generator rotor coil. It is used to generate a magnetic field in the generator rotor coil, then induces the stator coil to generate magnetic electricity.
Terminal N is the neutral point of the generator. It comes from the contacts of the three sets of windings of the stator coil. This column is used to check the charging light on the old car. There is no such column on the car currently, so the neutral point participates directly in the power supply. production inside the generator.
