When a fuse is blown and needs to be replaced, you can tell by checking if the metal strip inside the fuse is broken or melted. Additionally, the electrical device or circuit that the fuse is protecting may not work or may show signs of malfunction.
You know your car has blown a fuse if whatever the fuse is for suddenly quits working. For example if your radio is playing and for no reason quits it may be a fuse has blown.
I don't know specifically but there is almost never a large number of fuses in a car. It wouldn't hurt to check them all because any blown fuse would need to be replaced.
Well, I know when a tire on my car needs to be replaced when there is no tread left on it. What are YOU referring to
Pull it out an look at it. Most of the time you can easily see it is blown. If not check it with an ohm meter.
Put a continuity check on it. This can be done with an ohm meter. If there is no reading then the fuse is open.
If the speedometer works, but the odometer is not working, there could be a fuse blown if the odometer is digital. If the odometer is not digital, then a gear is broken in the speedometer cable. It should be replaced.
You can easily replace it but you need to know why it blew in the first place. All fuses are marked on the fuse box or in the drivers manual as to which circuit they protect. Determine which circuit that blown fuse protects and inspect that circuit for troubles.
the amp wont work.Check the power fuse first.If this is ok, there is generally another fuse inside the amp that will need checking
Can be just a blown fuse, so check the fuse. The lighter itself can be defective or the outlet can be bad. Try a known good lighter from another car and see if it works. If so, your lighter is bad. If not, then check the fuse. If the fuse is good you know you have a wiring problem or the outlet is defective and must be replaced.
In the event that you are discussing a wire free close by the circuit might look great with the visual test then, at that point, still coherence/ohmmeter test is required. Read More.. universalhc.ca/how-do-you-know-if-a-fuse-is-blown-in-the-furnace/
IS THE FUSE IN IT BLOWN? If not get a battery and a test light. You will probably have to cut the fuseable link out. touch one wire end to the battery and make a circuit with it, if the test light doesn't light up and the fuse isn't blown it is bad
if you know what fuse it will be blown if you look at it the small wire inside will be broke may even blacken the sides if not get a haynes manual from and local car shop and there will be diagrams in there for you to find the right fuse that may be broken but the biggest give away is that what ever it fuses wont work !
