Why does the car still not start after replacing the battery?

1 Answers

If a car with a newly replaced battery still fails to start, it could be due to a discharge fault in the vehicle's electrical circuit or poor battery charging. 1. If charging appears normal but the new battery loses power within a few days, there might be a self-discharge issue in the circuit, which should be checked with a multimeter. 2. If the battery regains charge after running the engine for a while, the charging system is likely functioning, but the rectifier might be damaged. 3. The battery, also known as an accumulator, plays a crucial role in starting the vehicle. If the battery is undercharged or dead, the car won't start. Therefore, battery maintenance should not be overlooked during routine vehicle care. 4. The primary functions of the battery are to store and discharge electricity, providing sufficient power for starting the car. When the battery malfunctions, the vehicle cannot start in cold conditions, and the electricity generated by the alternator during driving cannot be stored, potentially leading to symptoms like stalling in severe cases.

What Causes the Car Starter to Not Respond When Igniting?

Possible reasons for this issue include: 1. Power supply and transmission failure, or starter relay malfunction. During inspection, the first step is always to check the battery condition. You can turn on the headlights to observe their brightness. If the lights appear dim, it may indicate excessive battery discharge, loose connections, or poor contact. 2. If the battery is in good condition, check for relay faults: examine whether the relay coil has burnt windings or open circuits. Check if the relay contacts are severely burnt or fail to close. If none of these issues exist, proceed to inspect the starter motor. 3. Check whether the electromagnetic switch contact disc can properly connect both contacts, including verifying if the contact heights are uniform and inspecting for any burning. Examine whether the commutator is burnt, affecting poor contact with the brushes. Check if the brushes are grounded or have open circuits with the field windings. Inspect whether the field windings and armature windings themselves have open circuits, short circuits, or grounding issues. Finally, check if the armature shaft is bent or "eccentric."

Why does the AC turn on automatically when defogging is activated?

When the defogging function is activated in a car, the air conditioning also turns on simultaneously. This is designed to accelerate the removal of fog by utilizing the principle of the refrigeration evaporator condensing moisture inside the vehicle. Fogging on the front windshield typically occurs during winter or rainy days. Depending on the season, you can choose between hot or cold air: 1. Using cold air: This method is generally suitable for rainy days in summer. The operation is straightforward—simply turn on the cold air, adjust the vents to the front windshield, and activate the external circulation. This approach quickly and effectively eliminates fogging on the front window. 2. Using hot air: Turn on the hot air, select the front windshield as the vent outlet, and turn off the internal circulation. This method addresses the root cause of fogging but takes longer, making it less suitable for use while driving. However, over time, the fog will gradually dissipate, and the interior will become warm and comfortable, making it ideal for cold winter weather.

What is the highway fuel consumption of the Magotan?

The actual measured fuel consumption of the Magotan is around 9L/100km, based on user feedback. The official combined fuel consumption certified by the Ministry of Industry and Information Technology is 6.2L/100km, but actual fuel consumption may vary depending on the owner's driving conditions. The three main factors affecting fuel consumption are vehicle weight, car design, and driving conditions. There is a direct proportional relationship between vehicle weight and fuel consumption—it is said that a 10% reduction in weight can lead to a corresponding percentage decrease in fuel consumption. Relevant information about fuel consumption is as follows: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in standardized tests under constant-speed driving conditions. 2. Testing methods: The test can be conducted on the road or on a chassis dynamometer, and the fuel consumption per 100 kilometers is then calculated using the 'flow meter method' or 'carbon balance method.'

What brand of car features two parentheses inside a circle?

Beijing Automotive Group (BAIC). Below is extended information about BAIC: 1. Beijing Automotive Group Co., Ltd.: Established to fulfill the Beijing Municipal Party Committee and Government's strategic objective of 'mobilizing the city's resources to develop the automotive industry and build a first-class automotive R&D and manufacturing hub,' truly achieving the goals of advancing high-end manufacturing, strengthening the secondary industry, and transforming the capital into a world-class city. The company was jointly founded by six major enterprises including Beijing Automotive Industry Holding Co., Ltd. 2. Future Development and Strength: Under the theme 'Creating and Sharing the Future,' BAIC Group comprehensively showcased its achievements and future development capabilities in internationalization, new energy, intelligentization, connectivity, and sharing. This marked BAIC Group's official demonstration after rising to 137th place in the Fortune Global 500, representing its most complete industrial chain, largest exhibition scale, and leading position in the new energy vehicle market in recent years.

Can You Drive When the Engine Temperature Hasn't Risen?

You should not drive when the engine temperature hasn't risen. Here are the details: 1. After a car has been parked for a long time, the engine oil inside has mostly flowed back to the oil pan, and the oil film on the friction surfaces of the engine is largely destroyed. At the moment of startup, friction causes relative motion, but the oil pump hasn't yet delivered oil to the friction surfaces in time. This results in dry friction on the friction surfaces, meaning the engine experiences the most wear during the cold start phase. 2. Because low engine temperature increases engine wear, there should be a warm-up process after a cold start. After starting the vehicle, let the engine idle at a high speed automatically. Wait until the idle speed drops to the normal value (around 800 rpm) before driving. Before the engine temperature reaches the normal value, avoid exceeding 2500 rpm, keep the engine load under 30%, and refrain from aggressive driving such as rapid acceleration or hard braking. 3. Only after the engine temperature reaches the normal range (80°C--90°C) should you drive normally.

Why is the Toyota C-HR's body so heavy?

Toyota C-HR is essentially a product of Toyota's effort to enhance body strength while controlling costs as much as possible. The reason for its weight is the extensive use of high-strength steel, which is why vehicles based on Toyota's TNGA platform perform well in crash tests. A heavier body provides better stability at high speeds. Factors affecting a car's stability at high speeds include: 1. Vehicle tires: Tires are the only components in contact with the ground. Generally, wider and flatter tires improve stability at high speeds; 2. Vehicle shape: The vehicle's shape also affects high-speed stability. The more aerodynamic the vehicle, the better its stability at high speeds; 3. Drive configuration: Most vehicle drive configurations include front-wheel drive, rear-wheel drive, and four-wheel drive. Four-wheel drive vehicles are more stable than front or rear-wheel drive vehicles; 4. Suspension system: Generally, vehicles with independent suspension systems are more stable than those with non-independent suspension systems. Independent suspensions include MacPherson strut and multi-link independent suspensions, among others.
