Method of detecting whether the AC alternator is generating electricity
1. Testing method: Test whether the alternator generates electricity Method: Gently
touch an iron block on the surface of the pulley to test for magnetism. If there is
magnetism, the alternator can generate electricity normally. If there is no magnetism,
the alternator will not generate electricity
2. After installing the vehicle, use a multimeter to test whether the voltage, current,
and magnetic field are normal
Installation precautions for AC alternator
1.� Note that the negative electrode of the battery needs to be disconnected � (If
the negative electrode of the battery is not disconnected, there may be safety issues,
sparks, and other hazards.)
2. Pay attention to whether the endpoints of the upper and lower bearings are on the
same horizontal line
3. Pay attention to any unsafe issues such as protrusions or protrusions on the wire
connecting the wiring harness
4. When replacing the plug of the AC alternator and connecting the positive pole of
the AC generator, attention should be paid to the tightness of the connection
5. Pay attention to checking the parameters, match the number of pulley grooves
with the number of belt grooves, and pay attention to belt tightness during
installation
6. Adaptability: Use a 16 digit vin code to check the suitability of the car model (the
vin code is different for each car and is located at the bottom left corner of the
driver's seat under the wiper)
7. The assembled alternator should rotate flexibly, without jamming, scraping or
collision sound, and the rotor shaft should have no movement phenomenon
Daily Maintenance Methods for Automobile 1
Alarm light inspection
As the first step of routine inspection, instrument panel inspection is the simplest
maintenance inspection item. The vehicle undergoes a system self check during
startup. If any sensor sensing abnormalities or faults are found during the self check,
the vehicle's alarm light will light up. Sometimes, the owner may be careless and fail
to pay attention to the alarm light on the instrument panel. It may seem like a little
negligence, but its presence is very significant.
Lamp inspection
The inspection of car lights is the most common inspection item, and the importance
of brake lights is particularly prominent in car light inspection. At night, the
recognition of brake lights is a key factor in preventing rear end collisions.
Brake oil inspection
When checking brake oil, it is necessary to check the height of the brake oil level and
observe the color of the brake oil. Professional instruments will be used during the
inspection, which is still complex for ordinary users and requires professional
technicians to operate
Coolant check
The engine coolant needs to be replaced at a certain mileage, depending on the
mileage or duration of driving, as it is difficult to visually determine the degree of
deterioration. If the coolant deteriorates, its rust prevention quality will decrease, and
the radiator, pipelines, hoses, etc. will be damaged.
Battery inspection
At present, most of the batteries used in vehicles are maintenance free batteries, and
reliable use is one of its advantages. However, regular battery testing is still
necessary. You only need a multimeter to detect the actual battery level, and there
will definitely be high-power on-board appliances in the car during travel. It is
necessary to check the battery level in a timely manner.
Tire inspection
Tire inspection is the most important aspect of travel inspection. Firstly, a visual
inspection of the tire wall and tread is required to check for surface aging and wear.
The service life of the tire is approximately 4 years or 60-80000 kilometers, reaching
its service life. Even if there is no obvious damage to the side of the tire or the surface
does not reach the wear limit position, it needs to be replaced. The standard tire
pressure is generally marked in the B-pillar or fuel tank cover of the vehicle, If the tire
pressure exceeds or falls below normal, it needs to be deflated or replenished.
Oil inspection
Oil can be said to be the blood of the engine. When checking the oil, the first step is
to remove the dipstick and wipe it clean with a paper towel or cloth. After inserting it
into the engine and pulling it out again, check if the oil level is between MAX and
MN. If there is too little oil, it will cause severe engine wear and even cylinder pulling,
while if there is too much oil, it will cause suffocation

Car wash: It saves money and exercises the body. Every woman hopes her car is clean
and shiny, so she often goes to the car wash shop to wash the car. But have you ever
thought of washing the car yourself?
The pace of modern life and work is getting faster and faster, and many car owners
do not have free time to exercise. "Car owners can completely consider washing their
own cars as a unique fitness activity." Coach Liu from a certain fitness club said,
"Sprinkling, wiping, etc. are obvious whole body exercises that consume no less heat
than running Therefore, if conditions permit, using rest time and washing the car
yourself is also quite good. On the one hand, it can save money on washing the car,
and more importantly, it is also a good way to lose weight.
Interior hygiene: Regularly cleaning and changing the feeling of warmth in the cabin
comes first from cleaning, and doing a good job in interior hygiene is also the thing
that many female car owners are most willing to do. Especially for the sanitary dead
corners such as air vents, instrument panels, and storage compartments, it is
necessary to clean and disinfect the control panel, doors, and other areas with
specialized interior cleaning agents
Female car owners should start cleaning the car interior themselves from now on,
paying attention to protecting electrical equipment such as speakers, radios, CDs, etc.
from water ingress and corrosion. Car cushions and seat covers should be cleaned
more frequently, and it is best to prepare a few more sets. This way, changing them
every once in a while will also give your car a refreshing feeling
Daily Maintenance Methods for Automobiles Chapter 3
1. Daily maintenance content
(1) Appearance inspection: Before leaving the car, look around the car to see if the
lighting system is damaged, if the body is tilted, and if there are any leaks such as oil
or water. Check the appearance of the tires. Check the condition of the doors, engine
compartment covers, management compartment covers, and glass
(2) Signal device inspection: Turn on the ignition switch key (do not start the engine),
check the illumination of each alarm light and indicator light, start the engine, and
check whether each alarm light goes out normally, and whether the indicator light is
still on.
(3) Fuel inspection: Check the indication on the fuel gauge and replenish the fuel.
2. Weekly maintenance content
(1) Tire pressure: Check and adjust the tire pressure, and clean any debris on the tires.
Don't forget to check the spare tire
(2) Engine and various fluids: Check the fixation of various components of the engine,
check if there are any oil or water leaks on the joint surfaces of the engine, adjust the
tightness of the belt, check the fixation of the pipelines and wires in various parts,
