What does an auto fuse do?
Automotive Fuses: Almost everything in a car is wired through a fuse. Fuses are designed to fail when too much current is drawn through the device. This prevents heating of the wires and subsequent melting of the insulation, followed usually by fire!
Where is the fuse for the automatic?
Usually located in or around the instrument panel near the dash, fuses can also be found under the hood and even under the rear seat. Next time your radio, lights or other device stops working, chances are a blown fuse is the culprit. Look under “Fuses” in your owner’s manual for help finding your fuse panels.
What are the types of automotive fuses?
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.
Can a fuse look good but be bad?
Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it.
What are the big fuses in cars called?
Maxi/APX – These much larger fuses (29.2 × 8.5 × 34.3 mm) can hold more amps than standard or mini fuses. 20 to 120 amp. The classic ATC fuse is a plastic blade type. The amperage is noted by both the color and printed on the top.
Are all auto fuses the same?
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.
Can you drive with a blown fuse?
If the replacement fuse of the same rating blows in a short time, there is probably a serious electrical problem with your vehicle. Leave the blown fuse in that circuit, and have your vehicle checked by a qualified mechanic.
What are the small automotive fuses called?
Blade fuses
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.
Are all automotive fuses the same?
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.
