Can a fusible link be used as a fuse?
Fusible links are not rated in amps like fuses because each installation is unique and designed to meet specific circuit protection requirements. What size replacement fusible link should be used? The automotive service industry recommends using the same gauge and length as the blown fusible link after the cause of failure is corrected.
What kind of fusible link do I need for a 14 gauge wire?
A 14-gauge wire would be protected by an 18-gauge fusible link. A 6-gauge wire would be protected by a 10-gauge link, and so on. Odd number wire gauge sizes like 19, 15, 13 and 11 are counted when sizing a link.
How big should a fusible fuse wire be?
Odd number wire gauge sizes like 19, 15, 13 and 11 are counted when sizing a link. The length of a fusible link should not exceed 9″. Can a fusible link be used to replace a fuse that blows frequently?
How long does it take to replace a fusible link?
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. A starter motor or ECU? Not so much. But fusible links look much different than fuses and are used for different applications.
What should I do if I see a fusible link?
If this (or something similar happens), you should check for blown fuses in your fuse box first. If everything looks okay, pop the hood and inspect the wiring harness for melted, scorched, or broken wires. Don’t panic if you see one, as it may simply be the fusible link doing its job.
What’s the difference between a fuse and a fusible link?
Fusible links—also spelled fuseable and fusable—serve a similar purpose to a fuse. (You can read more about fuses here.) Just like a fuse, the link is designed to handle a lower current (amp) load than the rest of the system so, in the event of a short or overload, the link will be the first failure point.
Why are fusible links not rated in amps?
In an extreme current overload situation, the conductor within the link is melted while the ensuing flame and spark is contained within the link’s insulation. What are the ratings for fusible links? Fusible links are not rated in amps like fuses because each installation is unique and designed to meet specific circuit protection requirements.
When do fuse links need to be replaced?
When a fuse link has melted to protect a critical system from damage, it needs to be replaced before you can start your vehicle again. If you suspect a fusible link is the reason for your repair, check out O’Reilly Auto Parts. We carry fusible links to repair most vehicles.
