Is a fusible link the same as a resistor?
Is a fusible link the same as a resistor?
A resistor is a passive two-terminal electrical component, which provides some resistance to the flow of current. A fuse is a safety device, providing overcurrent protection of an electrical circuit. Many fuses are made from a resistor, which melts if too much current flows through it.
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 many AMPS is a 18 gauge fusible link?
18 gauge fusable links are rated at 14 gauge wire or 15 amps , 16 gauge are rated at 12 gauge wire or 20 amps. The fusible link that protects the wire should then be two gauge sizes (or four numbers larger).
Where are the fusible links on a GM Truck?
For what it’s worth, GM uses 5.0 mm sq. fusible links on their factory auxiliary battery option for the charging wire. Two, actually. One between the battery and the relay, and the other between the relay and the starter. In additon, GM has a 40 amp Mega fuse protecting the loads from the Auxiliary battery.
How big is the fusible link on a harness?
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.

How do you connect a fusible link to a car?
Check the fusible link. A fusible link is just like any other car fuse, but instead of being plastic, it is a thin wire with a thick insulator. To properly connect a fusible link you need to use a crimp, solder, and shrink-wrap the connection. Soldering Iron that is really good: http://www.amazon.com/gp/product/B002…
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.
