When does a fusible link fail what happens?
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.
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.
What do fusible links look like in Pico?
Pico makes fusible links and is nice enough to give each one a plastic tab with the wire gauge and “fusible” written plainly to see. (Image/Summit Racing) Well, that’s the fun part. They look like wires, which can make troubleshooting a headache—we’ll get to that in a second.
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?

Where to look for fusible links on a car?
When fusible links fail, they often lead to a no-start condition. 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.

Which is easier to install, fuse block or fusible link?
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 happens if you hook up a jumper cable to a car?
If one connects a strong battery to a vehicle’s electrical system with reversed polarity, nearly-unlimited current will flow through the alternator until it blows a fuse or fusible link, melts a wire or diode, or does something else catastrophic.
