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.
How is a wire measured in a fusible link?
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. Again, a fusible link’s function is very similar to a fuse. It’s designed to fail before your wiring harness melts to goo.
Why does my Grand Caravan not have a fusible link?
This particular model of Grand Caravan does not have a fusible link in the charging system. The reason given were the amount of relay, fuses and other safeguards installed in the system.
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.
Why are fusible links important in a circuit?
(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. When it fails, it will break the continuity in the rest of the circuit, preventing damage to other components down the line.
Do you need crimp connector for fusible links?
Many fusible links now come with a crimp connector pre-installed, which simplifies the installation process. Remember to weather-proof your connections—cover your joints with heat shrink tubing or tightly wrap your connections with electrical tape. Need a good 101 tutorial on electrical wiring?

What do you need to know about fusible links?
A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness designed to protect the harness in applications where a fuse is unsuitable. Universal 14 AWG Fusible Link
Can you replace wire with a fusible link?
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.
What causes the fusible link to blow on a car?
How much depends on the wire’s resistance, which correlates to its size. A fusible link is a “narrow spot” in your wire, a portion of higher resistance that will overheat, melt and break before the rest of your wiring does. Wiring has a certain amount of resistance — rated in ohms — per foot.
