What happens when a fusible link goes bad?
You will start seeing symptoms if that happens. Although the ignition will remain safe, you will face issues with the electrical components.

But if it is urgent or you want to do it anyway, we recommend you using mega fuses to get the job done.
What does the fusible link do?
The job of a fusible link is to provide safety and protection to the components. The fusible link does it by breaking the circuit in case of an overflow of current. You can say the function is more or less like the function of electrical fuses.
How long are the fusible links?
Well, there is no definite length of a fusible link. The length depends on the wire size of the conductor. Generally, the wire size of the fusible link is 4 gauges smaller than that of the original conductor. Plus, you should not use fusible links that are longer than 12 inches.
