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.

What does a battery fusible link do?
A fusible link is a special type of wire that protects a circuit that has constant high current requirements and must resist high surges in the circuit. The circuit between the alternator and battery is a good example of a circuit where a fusible link would be used.
What happens when fusible link goes out?
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.
Do I need a fusible link between alternator and battery?
Fusible link in the alternator charge wire would protect against a dead short in the alternator. Unusual, but it could happen. These links protect the car from the battery current. They are designed to go open in response to a dead short, without setting the rest of the car on fire or melting the harness.
What causes a fusible link to burn out?
Typically, a fuse burns out when a circuit attempts to transmit too much current, severing the connection before the electrical charge can have any ill effects. ... 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 long are fusible links?
The length of a fusible link should not exceed 9". Can a fusible link be used to replace a fuse that blows frequently? In general, a fusible link should never be used to replace an automotive fuse unless authorized by a vehicle factory service bulletin.
What fuse controls the alternator?
There are 2 fuses for the alternator. One is usually a fusable link (wire) for connecting the stator diodes to the battery, and a lower value fuse (10 to 30 amp) for protecting the field (rotor).
What causes a car to lose all electrical power?
Driving a car with a dead battery can also damage the alternator. ... The engine may not start, or you may suddenly lose all electrical power while driving. Ignition coil and other ignition components. Provides power to the spark plugs, and increases the voltage of the power provided to the spark plugs.
What does a fuse do?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.
What is a fusible link valve?
Fusible link valves are also known as thermal shut-off valves. They are an automatic shut-off valve that cuts of any gas or liquid in the pipeline once a fire is present.
What is fusible link fire damper?
A fusible link fire damper is a style of fire damper or smoke damper. ... Once the surround melts, the link opens, releasing the damper blades and shutting off access to the HVAC components and ductwork.
What is a maxi fuse?
Maxi fuses are larger than ATO/ATC fuses and offer protection for high amperage vehicle circuits. They are a blade-type fuse designed to replace fusible links or fusible wire. The fuse link is completely enclosed to help protect against moisture and other corrosive or damaging elements.
Can blown fuse drain battery?
a fuse blows to keep current from going through the circuit. in other words, there's no way a blown fuse can drain the battery. take the battery in to get checked, it might just be a bad battery.
How often do fusible links need to be replaced?
All Fusible Links shall be replaced once a year. The Links shall be replaced sooner during annual inspection if the conditions in (4) exist. The Fusible alloy that is used in the manufacturing of the Fusible Links undergoes a phenomenon known as Creep or Cold flow.
What temperature does a fusible link melt?
About fusible link's
The melting point of the alloy can be engineered to release at temperatures ranging from 135F/57C to 500F/260C. Our products comply with Underwriters Laboratories, Inc., Factory Mutual Research Corporation and NFPA Requirements.
