70a alternator

Types of 70a alternator

Alternators are electric generators that produce alternating current with the help of rotating magnetic fields. It's a crucial part of a car's electrical system. When the battery isn't enough to power the electrical system, the alternator comes in handy. The 70a alternators are generally used in vehicles with low electric power requirements. There are different types of 70a alternators, which include:

• Standard 70a alternator

  The ordinary 70a alternator is the most used in general-purpose vehicles. The alternator is low-cost and needs little maintenance and service. The 70a alternator is mainly used in cars with a basic electrical system and with no electrical accessories like heated seats, navigation screens, or extra lighting.

• High-output 70a alternator

  This is a 70a alternator that produces a higher current than the standard 70a alternator. The output is usually about 80 to 100 amps. The high-output 70a alternator is ideal for vehicles that have high electrical power needs, like trucks and commercial vehicles. The alternator can power electrical accessories like air conditioning, power windows, and infotainment systems. The construction of the high-output 70a alternator is a bit different. It has a larger rotor and more winding coils that increase its output. The bearings of the rotor are also improved to reduce wear and tear due to the increased friction caused by the larger rotor.

• Performance 70a alternator

  The performance 70a alternator is designed for high-performance vehicles like sports cars, luxury cars, and supercars. The performance 70a alternator is important in maintaining the vehicle's performance when the electrical system loads up. The performance alternator has a state-of-the-art cooling system, like cooling fins, to help the alternator cool down and maintain its performance by preventing overheating. The alternator also has a higher current output, which is about 100 to 120 amps. The performance 70a alternator has a lower rotor and frictionless bearings, which makes it generate less noise.

• Diesel 70a alternator

  Compared to petrol cars, diesel cars have more complex electrical systems. The 70a alternator used in diesel cars is designed to handle the high electrical power needs of the vehicles. The alternator produces a current output of about 80 to 100 amps. The 70a alternator also has a higher voltage, about 14 to 16 volts, to ensure that the electrical system runs smoothly and reliably.

Specification and Maintenance of 70a alternator

70a alternator is available in various specifications to suit different vehicle needs. Below are some of them:

• Voltage Rating

  The voltage rating of the 70a alternator is 12 volts. This voltage is vital for the smooth running of the electrical parts of the vehicle.

• Current Output

  The current output of the 70a alternator is 70 amps. This is the maximum current it can give out. The current output of the alternator is also referred to as the alternator rate.

• Rotating Speed

  The rotational speed of the 70a alternator is 6000 revolutions per minute (RPM). This is the minimum speed of the alternator to give out the rated current.

• Cooling Method

  The 70a alternator is cooled by air. The alternator has cooling vents that enable airflow to take place and assist in the cooling of the alternator.

• Size and Weight

  The 70a alternator is small and light. Its size is about 6.5 inches in diameter and 9 inches in length. This makes it easy to install and also transport. The weight of the alternator is about 10 pounds (4.5kg).

Below are some of the maintenance tips for the 70a alternator:

• Regular Inspection

  It is advisable to carry out regular inspections on the alternator to check for signs of wear. This will enable the early detection of any issues with the alternator before it becomes serious.

• Cleanliness

  Keeping the 70a alternator clean is a vital part of alternator maintenance. Cleaning the 70a alternator prevents the build-up of dust and dirt that can affect its performance.

• Tight Connections

  Check that all the connections of the 70a alternator are tight. Loose connections can cause current output fluctuations and also affect the performance of the alternator.

• Regular Belt Inspection

  Carry out regular inspections of the alternator belt to check for signs of wear. The alternator belt is very important because it connects the alternator to the engine. If the belt is loose or worn out, it can affect the performance of the alternator.

How to Choose 70A Alternator

Wholesale buyers should consider the following factors when sourcing 70a alternators for retail.

• Voltage Output

  The voltage output of the alternator is one of the most important factors to consider. Buyers should ensure that the alternator's voltage output is compatible with the electrical system of the target car. A 70A alternator has a voltage output of 12V and can charge batteries that are 12V.

• Physical Size

  The physical size of the alternator is also an important consideration. Different vehicles have different engine compartments with varying amounts of space. Buyers should ensure that the 70a alternator can fit into the engine compartment of the target car.

• Mounting Options

  Buyers should consider the mounting options of the alternator. Different vehicles have different types of mounting systems. It is important to choose a 70A alternator that is compatible with the mounting system of the target car.

• Rotational Direction

  The rotational direction of the alternator is another important consideration. Alternators can have a clockwise or anti-clockwise rotational direction. Buyers should ensure that the rotational direction of the alternator is compatible with the engine's rotational direction.

• Temperature Range

  Buyers should consider the temperature range of the alternator. Different regions have different temperatures. It is important to choose a 70A alternator that can operate in the temperature range of the target region.

How to DIY and Replace 70a alternator

Replacing a 70a alternator can be a straightforward DIY task for someone with basic mechanical skills. Here's a step-by-step guide:
