Go to your home's electric service panel - usually, a gray metal box on an interior wall of your basement or garage, near your outside electric meter. Open the door of the service panel and see if a circuit breaker is tripped (or a fuse is blown). If so, reset the breaker (or replace the fuse).

How do you test a fuse with a DMM?
Continuity test: Remove the fuse and check for continuity from end to end. Set your DMM to measure resistance, Ω, and probe both ends of the fuse. A good fuse will measure near 0 Ω, while a bad fuse will measure OL Ω or ∞ Ω. Test light: A high-impedance LED test light is one of the easiest ways to check automotive fuses.

How to check if a relay is faulty?
A relay can be checked with a jumper wire, voltmeter, ohmmeter, or test light. if the terminals are accessible and the relay is not controlled by a computer, a jumper wire and test light will be the quickest method. If voltage is not present, the relay coil is faulty. If voltage is present, continue testing.
How To Check Car Fuses In Simple Steps?
An electric fuse usually causes an electric short or an overloaded circuit. The most common fuse to burn out in a car is the 12v power outlet, also known as the cigarette lighter. This is often caused by leaving a cell phone charger in it for a long time, or because of the occasional stray penny that falls into an exposed power outlet.
How To Replace A Faulty Fuse?
After diagnosing a faulty fuse, it is important to fix or replace the fuse. Detect the damaged fuse and replace it with a fuse of the same type and amp rating. You can find to buy fuses of all types in most auto parts or hardware stores or dealerships.
How Much Would it Cost To Replace A Fuse?
Repairs and other similar jobs are quite expensive when it comes to the car industry. However, a fuse replacement job is luckily one of the cheapest repair jobs in this industry. Testing for a damaged fuse is quite easy and buying a new fuse will only cost about $2 US.
Conclusion
Following the steps provided in this article on how to check car fuses, can help you replace the fuse without much difficulty and very efficiently. If you are afraid of doing the job on your own, do not hesitate to get a mechanic to do the work for you.
How to check fuses in car?
There are several methods to check fuses in your car: Visual inspection; Testing with a multimeter; Using a circuit tester.
How to check if a fuse is melted?
First, connect one probe’s wire to the battery’s (-) terminal. Then, touch one contact pad of the fuse with the second probe’s wire. Repeat this action with the second contact pad. If one fuse terminal has a voltage and the other does not, it means the fusible element has melted.
What to do if fuse in car melted?
Inspect a fuse in your car to check its fusible element continuity. So, if the inside connector has melted, you need to replace the fuse. However, sometimes the wire may look intact even in the blown fuse.
How to test a circuit with a multimeter?
Testing with a multimeter. First of all, it is necessary to switch your tester to continuity mode (the icon typically looks like a sound wave). Then, touch both fuse’s contact pads with the multimeter probes. If the circuit is good, the tester will beep.
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.
How important is a fuse?
How important is this service? Fuses are resistors that send power to the electrical components of your car. Fuses receive a large amount of current, and lessen that amount of current before it is sent to each electrical part, so that the electrical components aren’t damaged by excessive power.
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.
What happens when a fuse blows?
When a fuse blows, electrical power will be not flow through it, and certain parts of your car will stop working. A blown fuse is unlikely to cause any damage to your vehicle, but the electrical components that rely on that fuse won’t resume working until the fuse is replaced.
Should I schedule an inspection for fuses?
Any time an electrical component of your vehicle stops working, you should schedule an inspection. There’s no way to perform regular maintenance on fuses, but they’re a straightforward and affordable repair when you notice that one is blown.
How to tell if a fuse is blown?
Then, probe both sides of the fuse. Both sides of a good fuse will show power, usually indicated by a red LED. If the fuse is blown, one side will show power, while the other side will show ground, usually a green LED. A note on impedance: Impedance is resistance to electrical flow.
What is an automotive fuse?
An automotive fuse is an overload safety device. Under normal circumstances, a certain automotive circuit might carry 5 A — ampere is a measurement of electrical current — while in use. Under certain circumstances, that current varies, so wire gauge is chosen at two or three times the expected load.
What does a blown fuse mean?
A blown fuse will show voltage on one side, but zero voltage on the other side. Voltage drop: Measure across the fuse, using both positive and negative probes. A good fuse will show 0 V, no voltage drop, and a bad fuse will show 12 V, full voltage drop, which means no voltage is available to the rest of the circuit.
Why is a fuse rated twice the load?
The fuse might be rated two times the expected load to allow for fluctuations during use. If something like an overload or short circuit occurs, the softer metal in the fuse overheats and melts, cutting off the rest of the circuit from current.
Can you remove a Bosch fuse with a needle nose plier?
Older glass-tube type and Bosch type fuses are round and can be removed with a fuse puller designed for them. Needle-nose pliers can be used, but carefully, as you could inadvertently cause a short circuit, which is why fuse pullers are made of non-conducting plastic .
Can you pull fuses out by hand?
Some fuses can simply be pulled out by hand, while others might require a fuse puller because they’re in tight spaces. Modern blade-type fuses are very common, such as APM, APR, ATC, ATO, ATS and APX, and can be removed with a fuse puller, usually close by in the fuse box.
