Types of Car Fuse

Plug in fuse
This is the most common fuse in the car, which looks like a small plastic piece with two pins inserted into the fuse box. Different colors represent different current sizes for easy identification.
Mini plug-in fuse: Smaller than ordinary plug-in fuses, suitable for small circuits.
Miniature plug-in fuse: Smaller in size, used in the latest models to save space.

Glass tube fuse
This type of fuse is cylindrical, with glass on the outside and metal caps on both ends. I used to use it more often, but now it's rare. The metal wire inside will melt when overcurrent occurs, protecting the circuit.
AGC fuse: It has a particularly fast response and protects sensitive equipment.
MDL fuse: The response is slightly slower, suitable for places where the current occasionally fluctuates.

Cylindrical fuse (PAL fuse)
This type of fuse is larger than a plug, like a small tube, suitable for circuits that require high current, such as power windows or heaters.
Low profile cylindrical fuse: Smaller, suitable for new cars with limited space.
High end cylindrical fuse: larger, protecting systems that require high power.

Bosch fuse (bullet fuse)
This type of fuse has a small bullet like shape and was commonly seen in some European cars, such as the old BMW or Mercedes Benz. It's not very common now, but it may be on old cars.

Maxi fuse
This is a large plug-in fuse used for high current systems, such as generators or high-power equipment. Usually placed under the hood to protect these high-power circuits.

ANL and ANN fuses
These fuses are highly resistant to high currents and are often used near batteries or generators. Suitable for systems that require high current, such as modified car audio or lighting.

JCASE fuse
This type of fuse is compact but can withstand high currents, and is used for power windows, power steering, etc. Smaller than Maxi fuses, but very powerful.

Current limiting fuse
This type of fuse is used in circuits with high current, such as commercial vehicles or industrial equipment, to protect the main electrical systems.

Variants of plug-in fuses (low type mini, low type mini)
Some small fuses used in modern cars are smaller in size and suitable for compact spaces.

Application of Car Fuse

Protecting electrical circuits and equipment

The core function of automotive fuses is to protect electrical circuits and equipment from damage caused by overloading. When the current in a circuit exceeds the fuse's rated current, the fuse will blow within a few seconds, blocking the current and protecting the circuit and connected equipment.

Prevents damage to electrical equipment

When the circuit current exceeds the fuse's rated current, the fuse blows to prevent damage to electrical equipment due to overcurrent, protecting vehicle appliances, electronic equipment and batteries.

Indicates circuit faults

A blown fuse can be used as an indicator of a circuit fault, helping the vehicle owner or service technician to quickly locate the problem and carry out the necessary inspections and repairs.

Improve safety

Fuses can prevent potential hazards caused by overloading the circuit in the event of an accident or emergency, for example, in the event of a vehicle collision, a blown fuse in the circuit can prevent dangerous situations such as a short-circuiting of the battery.

FAQ

Q: Why does the fuse keep blowing when replaced?

A: A blown fuse protects electrical euipment from over current and short circuiting. Fuses blow normally, however, once a fuse blows, it will reuire replacement by a similar kind of fuse. If the fuse keeps blowing, it indicates a more serious electrical problem that should be looked into by a vehicle mechanic.

Q: How to replace a car fuse?

A: First, one must determine which fuse has blown. Locate the fuse box to determine which fuse relates to the particular electrical euipment that has failed. Visually inspect the fuse for a broken connection or melted wire. Purchase a new fuse of the same type, size and current rating. Remove the old fuse and gently insert the new fuse in its place making sure not to damage the sensitive terminals. Replace the fuse box cover or panel. Test the new fuse and check if the electrical euipment in uestion is working correctly.

Q: What causes the fuse to spark when replacing it?

A: If there is excessive current flowing through the circuit the fuse will melt and the connection for the circuit will be broken. If the excessive current is too high for the fuse to handle, it will cause a massive spark.

Q: How to tell if a fuse is blown?

A: Remove the fuse from its holder. One may reuire a small screw driver to unscrew the fuse holder cover. Visually inspect the fuse. If there is a large gap in the wire or if the wire has melted and smeared the inside of the glass or plastic body, it means that the fuse is blown and needs replacement.

Q: Can a car fuse work intermittently?

A: If a fuse is working intermittently, replacing it will not solve the problem. A new fuse replacement may let the electrical component work temporarily, but unless the underlying cause of the disruption in electrical current is solved, the fuse won’t work for long and blow again.

Q: How many amperes fuse does a car stereo need?

A: The ampere rating of the fuse used for the car stereo depends on the current rating of the electrical euipment in uestion. If the car stereo has an internal fuse, then the fuse that is reuired at the fuse box should be a bit larger. For example, if the car stereo has an internal 20-amp fuse, then you should use a 25- or 30-amp inline fuse.

Q: How to test the car fuse with a multimeter?

A: Set the multimeter in continuity mode and attach the probes to the fuse terminals. This is an electrical test to determine if there is continuity between the terminals of the fuse. If the multimeter shows a large resistance, then the fuse is not connected and is most probably blown. The fuse will have to be replaced with a similar fuse of the same size, type and current rating.

Q: What causes a car fuse to keep blowing?

A: Eliminate the electrical euipment as the cause of the fuse blowing. Replace the faulty fuse. If the fuse blows immediately or it blows as soon as you turn on the electrical euipment then it is most likely a short circuit problem and not the electrical euipment.

Q: How to remove a car fuse with a tool?

A: Depending on the type of fuse, they may be small and delicate. Removing the fuse without damaging the nearby fuses or the fuse itself would be challenging. A fuse puller is a tool that can be used to make the process of removing a fuse much easier. This tool will help you remove the fuse uickly and cleanly.

Q: Where is the fuse box located?

A: Finding the fuse box that contains the defective fuse can be difficult. It is best to refer to the owner’s manual to determine the exact location of the fuse box relating to the electrical euipment in uestion. Some vehicles will have more than one fuse box. And the location will vary depending on model and manufacturer.

Q: Why has the fuse melted?

A: If the fuse itself has not blown but the fuse holder casing has melted, it indicates that the fuse holder was making a poor connection with the fuse. If the fuse holder has melted, it is because of a lost connection and not a case of over current in the circuit.

Q: What is the difference between ATC and ATO fuses?

A: ATC and ATO fuses are almost the same. The C in ATC stands for closed which indicates that the element is closed within the plastic housing. The O in ATO stands for open which means the element is open and subject to the environment.

Q: Why Do Car Fuses Blow?

A: Car fuses are designed to blow to protect electrical equipment in the event of overcurrent or short-circuiting. It is normal for fuses to blow but once a fuse has blown, it will need replacing as automotive fuses are single-use. If fuses in the same location are regularly blowing, further investigation may be required to determine the underlying cause for this action.

Q: What are the applications of automotive fuse?

A: Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems.

Q: What Types Of Fuses Are Available For My Vehicle?

A: Blade fuses are the most commonly used type of fuse in most vehicles. They have two metal prongs on either side that fits into the slots on your fuse box. They come in various sizes and shapes and have an amperage rating written at the top. To determine the type of blade fuses your vehicle uses, check your owner’s manual for a fuse box diagram. A fuse box diagram will show you what kind of fuse goes into each slot and the exact amperage to use. If you are unable to locate a fuse box diagram, consult with your local auto mechanic. They should be able to provide you with the necessary information and help you replace or install a fuse correctly.

Q: How Often Should I Replace My Vehicle's Fuses?

A: It’s common for fuses to become worn over time from regular use. If you discover a faulty or blown fuse, it is essential that you replace it as soon as possible. Replacing blown fuses can ensure optimal performance of your vehicle and promote the safe use of your vehicle.

Q: Are Fuses Specific To The Make And Model Of a Vehicle?

A: A fuse is a device that contains a strip of metal that melts when too much current passes through it. This strip of metal acts as a safety measure and prevents electrical components from being overloaded in the event of a power surge. Fuses come in various types and sizes, depending on the make and model of your car.

Q: How long does a car fuse last?

A: There's debate on exactly how long fuses last, with some manufacturers claiming fuses can last, 20, 30, even 40 years. However, in the auto industry it's recommended to check or consider replacing fuses after 10.

Q: Why are car fuses important?

A: Automotive fuses are used to protect the electrical circuits in your vehicle from overloads. They are designed to ``blow'' or disconnect the circuit if the current flowing through it exceeds the fuse's rating. This helps prevent damage to your vehicle's electrical system and wiring.

Q: Can a car fuse go bad without blowing?

A: It is possible for automotive fuses to go bad without blowing. They may become corroded due to moisture, but it very rarely happens. Most of the time, they just get blown. Even if fuse corrosion almost never happens, your automotive fuses are still worth checking out routinely to make sure they're all good.
