Another way to check a fuse is to use a multimeter or a test light, which are available at most auto-parts stores. Some national chains will even let you borrow one to quickly check a fuse box in their parking lot. The benefit of this method is that you don’t need to pull the fuse to check whether it has blown. Step 3: Install the New Fuse

How to check if a fuse has blown?
How to check the fuse? The easiest method is to visually inspect the fuse – if the fusible element inside the fuse is damaged, the fuse has blown. You can also check it with a multimeter. In “continuity mode”, it will emit a sound signal when the probes touch both of the fuse’s contact points if the fuse is good.

How to check a fuse while still in place?
If you don't want to break electrical continuity to components a fuse handles by pulling it out, a fuse can be checked while still in place using a voltmeter or a multimeter set to "V" (Volts). Note! Do NOT use a multimeter set to "Ohms" to test an electrically live circuit! With the ignition switch in the ON position, touch or clamp the black test lead to a good known ground.
How to test a fuse that has been removed?
Testing a fuse out of the vehicle can be done with a multimeter set to "Ohms" or continuity. Touch the red lead to one metal end of the fuse and touch the black lead to the other metal end of the fuse.
How to remove a fuse from a car fuse box?
Whatever their design, fuses will be clearly labeled with their ampere ratings. Physically remove the fuse using a small, specially shaped fuse puller tool. The tool serves to clamp around the numbered outer edge of the fuse that you can see. Some automakers include this tool within the fuse box.

What is a fuse box?
Fuses, found in the fuse box, are low-resistance resistor devices that protect the circuits in the car from excessive current. Fuses are made to blow if the circuit gets more current than it is supposed to, protecting the circuit from the high current flow.
What does it mean when a fuse blows and then blows again?
If a fuse blows, is replaced, and then blows again, it indicates a problem with the electrical system. Something is causing the overload. Be sure to have the car inspected.
How to tell if a fuse box is blown?
If you see a curving wire intact from one post to the other, it is good. If it is blown, you will see the wire burned through and a burn mark around it.
What is a fuse?
A fuse is a very robust and simple device: try to carry too much current and this little bit safely melts and that interrupts the circuit. Melting is what “fuse” means.
What does a smog tech see after you clear the code?
Now for what the smog tech “see’s” after you clear the code without fixing the issue. The protocol that the scan tool uses is called IM ( short for inspection and maintenance). Your car continually checks that all the systems are working correctly. if one is not it will set a check engine light on. Hard faults such as failed sensors or actuators, hard engine misfires and disconnected devices will generally reset the light very quickly. If your car takes awhile to turn it back on the problem is more likely in the evaporative loss system or catalyst system. both of these system require long drive cycles under specific conditions to perform and complete their tests. I have seen vehicles that traveled over 300 miles before resetting the check engine light because it took that long to meet the test conditions.
What to do if you don't want to fix the light?
The only thing you can do, if you don’t want to repair the issue, is purchase a cheap code reader that also clears codes, and keep it in the vehicle. Keep in mind, when you don’t repair the cause of the first problem that turned the light on, you could end up missing a new and more serious problem.
Can a car pass a smog inspection?
Your car WILL NOT EVER pass a smog inspection unless all the IM tests are completed and have passed. When they have all passed you wont have a check engine light on. This is cut and dry. There is no room for discussion with the smog guy. it is actually a very black and white process.
Can Autopart Store check fuses?

Test the fuse. Listen for the multimeter to beep continuously as you hold the probes against the fuse. If you don’t hear any noise coming from the meter, then the fuse is blown and should be replaced.
Why are my fuses black?
They are made clear so that you can see if the wire remains intact. If the translucent area is blackened, it is usually because the fuse has burned out. However, some fuses will create that blackened stain after only slightly overheating, and that may have even been the result of an unnoticed incident weeks or months earlier. If a device is not working, you should test the fuses. If the fuses are all still working, there is likely a more serious problem and it may be time to call on an expert.
How to tell if a fuse is positive or negative?
Put one lead on each end of the fuse and look at the display. Because the fuse is little more than a single wire—and no complex parts to worry about—it does not matter which side receives the positive or negative lead.

What does a fuse do?
Fuses are really just wires that are designed not to last, but their purpose is to prevent damage to more valuable electrical equipment or prevent fires (especially in homes) caused by power surges. If too much power runs through the fuse, it will "burn out," quite literally, and open the circuit, preventing the current from flowing through the circuit. There are several varieties of fuses, but their differences are primarily in appearance. Here is a description of the two you are most likely to see:
Why do cars use fuses?
Cars and older homes that don’t use modern circuit breakers use fuses to prevent damage from electrical surges. Sometimes these fuses require testing to check that they are still in good working order. Testing fuses can be done using a multimeter, and doing so is both fast and easy to learn.
What is a fuse link?
Fuses, fuse links, and circuit breakers protect your vehicle’s electrical system from overloading. If electrical parts in your vehicle are not working, the system may have been overloaded causing a blown fuse or tripped circuit breaker.

How to check if a fuse is broken?
Check the fuses for charred glass or broken filaments. See if there’s a diagram or labels on the inside of the panel door. If you’re lucky, you’ll be able to look up the room where the power went out and track down the corresponding fuse. Twist that fuse counterclockwise, pull it out from the socket, and look inside the glass for black marks or a broken filament wire.
What to do if fuse box is unlabeled?
If your fuse box is unlabeled, check each fuse individually for charred marks or broken filaments. Once you’ve found the one that blew, label it! If you label your fuses every time you replace one, you’ll eventually have a full diagram of the box.

When you’re ready, flip the main fuse switch or reinsert the main block to restore power to your home. Then test the circuit by checking the lights or plugging in your electronic devices.
How to find a fuse that stops working?
Find the fuse that controls the device that’s stopped working. Lift the latch on the side of the fuse box to loosen the cover.

Your manual may also include a diagram but, if all else fails, you can also find information on your specific vehicle online.
What happens if a fuse blows again?
If the fuse blows again soon after you replaced it, you may be using more electrical devices than the circuit can handle. Try using fewer devices or unplug non-essential appliances when they’re not in use.
What does a fuses look like?
Older homes have glass fuses that look like light bulbs. When fuses blow, they need to be replaced. Newer homes, on the other hand, have circuit breakers instead, which just need to be flipped and reset.
