Can a Blown Fuse Prevent Car From Starting?
Anyone that owns a car will know that every now and then, something will go wrong, and you will need to fix it. One of the most common faults of a car is that it won’t start, which can be really annoying if you were in a hurry to get somewhere.
There are some more common things that could explain why your car is not starting, like a dead battery, but there also other reasons that could explain why this is happening.
If your car is getting to that older stage of life and it has served you well for a long time, then you can be sure that at some point, one of your fuses is bound to blow. If you are really unlucky, then multiple fuses could blow at once, and this can cause some issues that will need fixing.
We are going to talk you through all of the things that can be caused by a blown fuse, and even give you some alternative reasons why your car might not be starting.
Can a Blown Fuse Prevent a Car From Starting?
Typically, when a fuse is blown in your car, it will usually cause a minor electrical problem, and this will typically be easy to fix. Such electrical problems can include your backup or interior lights not working properly, or even the loss of radio power or a missing turn signal.
In rare cases, though, a blown fuse can mean that your car won’t start. However, in some rarer cases, a blown fuse can actually prevent your car from starting, and just because it is rare, it doesn’t mean that it won’t happen to you.
Things That Can Cause a Fuse to Blow
If the problems just keep on adding up, then it is more likely that there is something more seriously wrong with the wiring in your car.
If multiple things are going wrong, all at the same time, then you are more than likely going to have to go and see a car mechanic, as this is the only way you are going to be able to get to the bottom of the issue. However, if it is just one thing going wrong, then it is much more likely to be due to a blown fuse.
Each and every car uses fuses, and if any electrical problem does occur, then it is likely that it is because of a blown fuse. A blown fuse is basically when the fuse has heated up, melted, and then proceeded to interrupt the flow of the electricity, which is what is likely causing you problems.
Sometimes, if a fuse is blown, it can mean that you have an even bigger problem on your hands, but it can also be due to much simpler reasons. One of these simple reasons could be if the driver has overloaded the system by using too many different features at one time.
Another reason that a fuse can blow is that a faulty fuse has been replaced with one that is too high of an amperage. The most common types of amperage that you will find with fusing are 15, 20, and 30, and if you were to replace a 15 amp fuse with a fuse that has a higher amperage, then it can definitely result in a blown fuse.
If luck really isn’t on your side, then it could cause even worse problems, as it can lead to the melting of different wires.
On the opposite side, if you change a higher amp fuse with one that has a lower amp, then it probably won’t be able to provide enough power to the component that has stopped working.
Signs of a Bad Starter
There are two things that will tell you if you have a failing starter, and they are:
- Your vehicle cranks slowly or it struggles when starting. This is typically the first sign that you have a problem with your starter.
- The vehicle will not start at all when you turn they key or push the button, depending on which type of starter you have
What Fuse is the Problem if My Car Won’t Start?
If a fuse has blown in the starter circuit, then this could be a big cause for the car not being able to start. Other issues that could result from a blown fuse are broken or corroded wiring, as damaged wires to the battery or the starter can prevent a sufficient amount of power from reaching the starter.
If your car won’t start, but all of the lights still come on, then it is most likely due to a blown fuse of fusible link, a bad starter, or a dead battery. All of these things could show these symptoms, and only some of them are a quick and easy fix.
The first one that you should try to rule out is a dead battery, as this is the easiest one to solve. If you try to jump start the car and nothing happens, leaving you with a car that still won’t start, then it likely isn’t anything to do with the battery.
If the battery is still in good condition, then there is no reason why it wouldn’t be able to start when supplied with enough power. Once this has been ruled out as the main problem, you know that it is something else entirely, and this will need to be checked out.
Signs of a Blown Fuse
If you have owned your car for long enough, then unfortunately, it is only a matter of time before you experience a blown fuse. A blown fuse will typically cause a minor electrical problem, and the source of this depends on which fuse has blown.
It could affect your radio, lights, or even indicators, depending on the fuse in question. If it is just one thing that has stopped working, then you might be able to fix this on your own, but for multiple issues, it is best that you take it to a mechanic to get to the route of the problem.
