How do I know which fuse to use in 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 put a 20 amp fuse in a 15 amp car?
The 15 amp slot is designed for handling current upto 15 amps so if you put a 20 amp fuse in a 15 amp slot and draw a current greater than 15 amps there will be heating and other issues like molten insulation you can put a 20 amp fuse only if u know that u are not going to draw more than 15 amps.
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.
What size are my car fuses?
Size groups
| Blade size | Blade group | Common ratings (maximum current) |
|---|---|---|
| Micro3 | ATL | 5, 7.5, 10, 15 |
| LP-Mini (low profile) | APS, ATT | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
| Mini | APM, ATM | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
| Regular | APR, ATC, ATO, ATS | 0.5, 1, 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30, 35, 40 |
What happens if you use the wrong fuse in a car?
Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. 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.
Are car fuses interchangeable?
A fuse is composed of a housing, fuse element and contacts, and they vary in size and configuration. They come in either blade or cartridge-style. ATO fuses and ATC fuses are regular-sized automotive blade fuses. They are interchangeable, provided the amperage rating is the same.
What happens if I use a bigger fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
What are the smaller car fuses called?
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.
Is it OK to use a bigger fuse?
Can a car fuse go in either way?
Fuses can be used either way around, there is no difference between the ends.
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 are the different types of fuses used in cars?
Most automobile fuses used in vehicles today are one of three types: mini, standard or maxi. The mini and standard are fast-acting fuses that protect the majority of your vehicle’s circuits, including those for lights and radios.
What does the fuse box do in a car?
Just like in your home, your fuse box controls the electrical flow, or power, throughout your car. Every car uses fuses to protect the vehicle’s wiring and electrical system components. There are four main fuse types found in vehicles today: Low-profile Mini, Mini, Micro2, and ATO.
Where can I buy spare fuses for my car?
Before you buy and replace car fuses, keep in mind that the fuse panel cover often contains spare fuses and even a fuse puller. Just be sure to replace the spares so they’ll be there the next time you need them. You can buy them at any auto parts store and at well-stocked service stations.
What should I do if my car fuse is not working?
If the fuse isn’t broken, check the condition of the fuse connectors in the fuse block. Also check for any melting that may have occurred due to a short circuit. If you need a new fuse block or fuse panel for your vehicle, check out O’Reilly Auto Parts. We carry fuses, fuse blocks, and fuse holders for most cars, trucks, and SUVs.
