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.
How does a fusible link work like a fuse?
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. A fusible link acts much like a fuse; only it’s designed to handle a different type of potentially hazardous scenario.
Why does my TCM fuse blow when I start the engine?
Unplug those sensors. The ignition coil and injectors are in this circuit. They are turned off by the Engine Computer removing their ground circuits, so even if one of those parts were shorted, the fuse wouldn’t blow until you started cranking the engine. That eliminates the coil and injectors as suspects, but not the wires going to them.
What to do if your fuse blows on your car?
Look for a wiring harness that fell down onto hot exhaust parts. If everything looks okay, unplug the O2 sensors, then if the short appears to be gone, reinstall the ASD relay and fuse then try to start the engine.

When did the fusible link first come out?
You’ve got to love the old-school fusible link. A study in simplicity that even a child could understand, the fusible link dates back to a simpler time before cars used junction boxes or complex computer controls.
How big of a wire do I need for a fusible link?
A 50-amp amplifier mounted in the trunk 15 feet from the battery would need a 4-gauge wire, which is good for 70 amps at 16 feet. For the fusible link, add 10 to 15 percent to the accessory draw. In this case, you’d need a link rated at 55 amps, primarily because you’ll have a hard time finding one rated at 57.5.
How is a fusible link like a weak link?
While fusible links can be a bit of a pain if you don’t remember where they all are, they do make diagnosis a lot simpler once you locate them. A fusible link is essentially a fuse set directly in line with the wiring and works as much like a literal weak link in the chain as you can imagine.
What should I do if my Nissan Altima fuse is not working?
If a new fuse also opens, have the electrical system checked and repaired by a Nissan dealer or a repair facility of your choice. If any electrical equipment does not operate and fuses are in good condition, check the fusible links. Never use a fuse of a higher or lower amperage rating than that specified.
Why does my Nissan 350Z have a blown fuse?
Fuses and fusible links protect your vehicle’s electrical system from short-circuiting or overloading. If electrical parts in your vehicle are not working, the system may have been overloaded causing a blown fuse. Before you replace or repair any electrical parts, check the appropriate fuses.
Where is the EVAP canister on a Nissan Altima?
EVAP Canister Purge Volume Control Solenoid Valve, EVAP Canister Vent Control Valve, Intake Valve Timing Control Solenoid Valve (VK35DE), VIAS Control Solenoid Valve (VK35DE) It is near the battery. Remove the fuse box cover by pushing the tab and lifting the cover up.
