How much smaller should fusible links be?
How much smaller should fusible links be?
Typically, a given harness segment is protected by fusible link that is four gauge numbers smaller. 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.
Where do I put the fusible link?
They are placed in-line between delicate harnesses and large sources of electrical current in your car—between the battery and alternator, for example. These links must transmit high-current electricity, but also protect the rest of the electrical system from dangerous spikes that could cause a fire.
How big of a fusible link do I Need?
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. The length of a fusible link should not exceed 9″. Can a fusible link be used to replace a fuse that blows frequently?
What kind of wire is protected by fusible link?
Can a fuse be swapped in for a fusible link?
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.
Where does the fusible link end in a harness?
The link may be at the very end of the harness as well, ending at a ring terminal secured to a solenoid, battery, or motor. When a fusible link does its job, it will break the circuit continuity, which is akin to cutting the wire.
