Can I replace a fusible link with a fuse?
To replace the fusible links with fuses you will have to use mega fuses, the smallest will most likely be about 50 amps. And this will take up a lot of room, and be more connections to go bad. What does a fusible link do? A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable.
What is a fusible link and how do they work?
Fusible Link: A temperature sensitive device that holds the damper components in the open position, which in turn, allows air to pass through. When the fusible link opens, it releases the damper components to close, and they will stay closed until a new fusible link is installed.
Can a fuse replace a fusible link?
It is difficult to replace fusible links with fuses. Fusible links are compact and handle a lot of current before they blow. To replace the fusible links with fuses you will have to use mega fuses, the smallest will most likely be about 50 amps. And this will take up a lot of room, and be more connections to go bad.
Why a fusible link and not a fuse?
A fusible link acts much like a fuse, only it's designed to handle a different type of potentially hazardous scenario. These links are actually strands of wire wrapped in a fireproof covering, and are thinner than the wiring harnesses they're connected to.
What is the purpose of a fusible link?
A Fusible link is a short, low-voltage wire that acts as a fuse in a vehicle's wiring harness. Fusible links provide circuit protection in the wiring of a vehicle in the case of a short circuit or voltage spike. These insulated wires may be used in applications in which an automotive fuse is unsuitable.
How can you tell if a fusible link is blown?
The fusible link is essentially an in line fuse on the positive terminal of the battery. To determine if the fusible link has been blown , one test lead of your ohmmeter should be on the positive terminal of the battery and the other test lead should be on the end of the fusible link going to the circuit it protects.

A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable.
What happens when a fusible link blows?
If the alternator's fuse or fusible link is blown, the alternator will not be able to charge the battery. The battery then doesn't store enough power for starting the car or keeping it running.
What amperage is a fusible link?
All I could find about fusible links is that they where always used in applications over 30 amps. So if we use the marine wiring specs, for your 12 guage wire they say it can handle 45 amps(in house wiring that same wire would be rated for 20amps).
Why wont my car start if it's not the battery?
If your vehicle won't start, it's usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you're dealing with a battery or an alternator problem. Here's how to know which one is the culprit.
What happens when the fusible link goes bad?
When it fails, it will break the continuity in the rest of the circuit, preventing damage to other components down the line. A fusible link typically costs a couple of bucks and can be replaced in 30 minutes.
How does a fusible link valve work?
The fusible link portion is the linchpin of the assembly and keeps the fire safety valve open by keeping tension on a spring pack through the trigger assembly. When a fire breaks out, the link separates when its rated temperature is met, releasing the spring pack and allowing it to close the valve.
Are fusible links color coded?
Color coding is standard almost across the board for different types of automotive blade fuses, with two notable exceptions: 25 A and 35 A maxi fuses. These are gray and brown, respectively—colors that are also used for lower-amperage fuses.

What About Fusible Links?
In automotive applications, a fusible link is a length of wire that is several gauges thinner than the wire that it is designed to protect. When all goes well, this results in the fusible link failing and breaking the circuit before the protected wiring can fail.
What is a fuse in a car?
Automotive fuses are the gatekeepers and bodyguards of automotive electronics. Whenever a sudden short or surge threatens the electronics of a modern car or truck, a fuse stands ready to throw itself into the fire.
How many types of blade fuses are there?
Types of Blade Fuses. There are six types of blade fuses that you may run into when you pop open the fuse box on a modern car or truck: micro2, micro3, low-profile mini, mini, regular and maxi. For all blade fuses, the housing may be opaque or clear.
How to tell if fuse is bad?
When the housing is clear, it's usually easy to tell whether the fuse is bad because the metal strip that connects the two terminals is visible. If the strip is broken, the fuse has blown.
What is the largest type of blade fuse?
There are many different types of fuses, but most modern cars and trucks use one or more of the following types of bladed fuses, in descending order of size: Maxi (APX) heavy-duty fuses: The largest type of blade fuse. Used in heavy-duty applications. Available with higher amperage ratings than other blade fuses.
Where to find amperage rating on fuse?
Look at the top of the fuse for the amperage rating printed on or stamped into the plastic.
When did mini fuses start replacing ATO fuses?
Many applications started to replace ATO and ATC fuses with mini fuses in the 1990s, but they are still widespread.
What is fuse link?

What is fusible link?
The fusible link is just a piece of wire. It was cheap, quick, and simple, but inaccurate in the protection it provided.
What happens when you use a fusible link?
Don't forget that if you use a normal piece of wire in place of a fusible link,the insulation will melt before the wire burns thru leaving it open to a direct short. When a fusible link burns out, the insulation stays intact.
How big can a fuse be?
You can size a fuse up to the point where the wire gets so hot it will begin to light things on fire. This will be much larger than just the maximum continous current of the fuse.
Why is a fusable link not a crimped link?
If connected with a crimped and soldered connection, a fusable link wouldn't have the potential problem of corrosion an the connections where a fuse would be plugged in.

The fusible link is a very important item in the vehicle, if it goes bad, it can literally leave you stranded in the middle of nowhere. After all, it feeds, all of the interior lights, equipment and starter solenoid.
What happens when a fuse holder breaks?
Corrosion, heat and vibration will take their toll on that fuse holder and if it is a cheapo to begin with, well let's just say I hope you don't mind being stranded when it breaks.
Can you put a bigger fuse than what should be?
In my opinion there would be nothing wrong with an actual fuse IF you calculate the total current drawn--NEVER NEVER EVER PUT A BIGGER (HIGHER RATED) FUSE THAN WHAT SHOULD BE !. i.e. If the maximum the wiring harness is meant to handle oh let's say 30 amps, use a 30 amps or less, not 40 or 50 or you'll have a nice electrical fire possibility.
What is a fusible link?
As a general rule, a fusible link is made of wire that is four gauges higher (smaller) than the rest of the circuit, making it the weakest link in your electrical chain. For example, a fusible link in a 10-gauge wire would be 14-gauge.
How Does a Fusible Link Work?
Wire is measured in “gauge,” often abbreviated AWG for “American Wire Gauge.” The lower the number, the bigger the wire. Bigger wires handle more current (amp) draw. Check out this cable calculator chart to learn more.
How many gauges are fusible links?
Remember, a fusible link is going to be four gauges higher (smaller) than the rest of the circuit.
How long does it take to replace a fusible link?
A fusible link typically costs a couple of bucks and can be replaced in 30 minutes.
How to check continuity of a circuit?
You can also check for electrical continuity using a multimeter ‘s continuity setting. Clip a lead on one end of the circuit and the other to its opposite end. If continuity exists, then your problem is likely elsewhere.
What to look for when combing a wiring harness?
When you’re combing over your wiring harness, you’ll want to look for a short section of wire (usually a few inches long) that has a smaller diameter than the wire into which it’s connected. There’s also a good chance that the link will be a different color than the wire.
Is a fixed rated fuse better than a dedicated fuse block?
But certain automotive components require momentary higher peak current levels depending, so a fixed-rating fuse may not be ideal. Fusible links are also cheaper and easier to install than a dedicated fuse block, which is why you see them in OE applications.
What is a fusible link?
A fusible link acts much like a fuse; only it’s designed to handle a different type of potentially hazardous scenario. These links are actually strands of wire wrapped in a fireproof covering and are thinner (smaller gauge) than the wiring harnesses they’re connected to.
Why are fusible links so frustrating?
Fusible links can be frustrating to diagnose and repair because their damage can be impossible to detect with a simple visual inspection. When fusible links fail, they often lead to a no-start condition.
How long should a fusible link be?
The length of a fusible link should not exceed 9″.
Why does a fuse burn out?
Typically, a fuse burns out when a circuit attempts to transmit too much current, severing the connection before the electrical charge can have any ill effects.
Why do electrical links melt?
These links must transmit high-current electricity and protect the rest of the electrical system from dangerous spikes that could cause a fire. If there’s a surge, the link actually melts, as its resistance to heat is lower than that of the circuits it’s protecting. This cuts off power while protecting the engine bay from a fire, thanks to its fireproof wrapping.
Where to find wires on a car?
On an older vehicle, the first place to look for these links is under the hood near the battery or along the firewall — look for a length of wire that is roughly two gauges smaller than the harness it’s connected to.
Does a wire wrap have a fusible link?
The wrapping might feel more rubbery to the touch compared to other wires around it, and it could also have “Fusible Link” printed on it every few inches or so and sometimes tagged with “Fusible Link.”
How to find a fusible link in a car?
On an older car, the first place to look for these links is under the hood near the battery or along the firewall. You should search for a length of wire that is roughly two gauges smaller than the harness it’s connected to. The wrapping might feel more rubbery to the touch compared to other wire, and it could also have ‘fusible link’ printed on it every few inches or so. Once you locate it, you can replace the length of wire with a fusible link that matches the gauge of wire called for by the original design. Don’t try to save a few pennies by simply swapping in a thin gauge wire, as standard wire lacks the protective insulation of a link and could lead to a short-out condition if the strands inside melt away their covering. Swapping in an inline fuse may also be tempting, but a fusible link is there for a reason, so trust the vehicle’s engineers.
Why are fusible links so frustrating?
Fusible links can be frustrating to diagnose and repair, because their damage can be impossible to detect with a simple visual inspection. Additionally, given that they’re designed to interact with high-current electrical components, when they fail, they often lead to a no-start condition.
Why does a fuse burn out?
Typically, a fuse burns out when a circuit attempts to transmit too much current, severing the connection before the electrical charge can have any ill effects. A fusible link acts much like a fuse, only it’s designed to handle a different type of potentially hazardous scenario.
How does a fuse work?
A fuse serves as a link in your vehicle’s electrical system that can be broken under certain circumstances in order to protect various components and systems from damage.
Why does a link melt?
If there’s a surge, the link actually melts, as its resistance to heat is lower than that of the circuits it’s protecting. This cuts off power while protecting the engine bay from a conflagration, thanks to its fireproof wrapping.
Can you swap in an inline fuse?
Swapping in an inline fuse may also be tempting, but a fusible link is there for a reason, so trust the vehicle’s engineers. While sometimes difficult to detect, fusible link issues shouldn’t keep you off the road for long.
