Not all car fuses are the same, and most cars have multiple fuses of varying sizes for different electrical components. When you are replacing a car fuse, it is essential to replace the blown fuse with a new one of the same type and size. You should also never replace a blown fuse with one of a higher amperage rating.
How do I know what fuse I need for my car?
Look under “Fuses” in your owner’s manual for help finding your fuse panels. Most manuals have a diagram showing you where each fuse box is. Each fuse panel cover should have a diagram listing each device and the corresponding fuse.
Can you use a different fuse in a car?
It’s possible to replace any ATC fuse with any other ATC fuse, any mini fuse with any other mini fuse, and so on. However, this isn’t safe if you don’t match the current ratings. Although fuses can blow under normal operating conditions because of age and wear, a blown fuse often indicates a deeper problem.
What are the different types of fuses for cars?
There are 4 main types of fuses: Micro, Mini (APM, ATM), Standard (APR, ATC, ATO), and Maxi (APX). Each fuse can be color coded with the appropriate amperage rating on top. Micro: Smallest type of blade fuse.
What happens if you put the wrong fuse in a car?
If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.
What are the 3 types of fuses?
Different Types of Fuses – Constriction, Working & Characteristics
- DC Fuses.
- AC Fuses.
- Cartridge Fuses.
- D – Type Cartridge Fuse.
- HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
- High Voltage Fuses.
- Automotive, Blade Type & Bolted Type Fuses.
- SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.
What size are my car fuses?
|Blade size||Blade group||Dimensions L × W × H|
|LP-Mini (low profile)||APS, ATT||10.9 × 3.81 × 8.73 mm|
|Mini||APM, ATM||10.9 × 3.6 × 16.3 mm|
|Regular||APR, ATC, ATO, ATS||19.1 × 5.1 × 18.5 mm|
|Maxi||APX||29.2 × 8.5 × 34.3 mm|
Are ATO and ATC fuses interchangeable?
ATO fuses and ATC fuses are regular-sized automotive blade fuses. They are interchangeable, provided the amperage rating is the same. The housing can be open or closed, but neither is sealed or waterproof.
Again, a fusible link’s function is very similar to a fuse. It’s designed to fail before your wiring harness melts to goo. As a general rule, a fusible link is made of wire that is four gauges higher (smaller) than the rest of the circuit, making it the weakest link in your electrical chain.
Should I replace all the fuses in my car?
Replacing all the fuses should not cause any problems with your car, unless you get the fuses wrong, or don’t fully seat them etc. On balance, much better off just testing them all with a meter. Most fuses have two exposed bits of metal on the top so you can even check them without removing them.
Do fuses come in different sizes?
Sizes and Amperages
Blade fuses (shown at right) come in six sizes, which are, from smallest to largest: Micro2®, Micro3®, Low Profile MINI®, MINI®, ATO®/ATC® (also called “regular”) and MAXI® or MAX.
How do I know what kind of fuse I have?
Look for “Class G” printed on the fuse. These fuses can be recognized by either their round shaped bodies with or without blades. Look for the wording “One Time Fuse” printed on the fuse. These fuses can be recognized by a removable slotted end cap that can be removed so that the fuse material can be replaced.
What are the standard fuse sizes?
Manufacturers have now standardised plug fuse ratings to be either 3A or 13A. However, 5 Amp fuses are still used in some older equipment and are available to buy.
Can I replace a 15 amp fuse with a 20 amp fuse in my car?
It would not be a good idea to replace a 15 amp fuse with a 20 amp fuse. If you do and you actually load to circuit to more than 15 amps, you will shorten the life of the insulation and increase the risk of a fire.
Can I use a 10 amp fuse instead of 13?
There is a reason they specified a 10Amp fuse and nothing more. If you replace it with a 13 amp fuse, you will run the risk of not being able to protect your TV against a malfunction which sometimes may cause excessive heat and even fire.
Can I use a 15 amp fuse instead of a 10 amp fuse?
Yes you can use any fuse with a lower amperage but it may not last very long you should replace it as soon as you can with the proper size.
