What does a 175 amp mega fuse do?
Product description Designed and patented by Littelfuse, the MEGA Fuse is ideal for battery and alternator protection application and other heavy gauge cables requiring ultra-high current protection. Slo-Blo feature eliminates nuisance blowing during temporary short duration overloads.
What are mega fuses for?
A MEGA® fuse is a bolt-down fuse designed for use on high current or heavy-gauge applications. Examples include battery or alternator protection for when a MEGA® fuse would come in handy. MEGA® fuses are available in a higher amp range versus standard fuses, making them the go-to for high-amp protection.
How can you tell if a mega fuse is blown?
Place the leads across the fuse and observe the reading.
- A good fuse will read less than 20 ohms, depending on the fuse rating.
- If the fuse reads much more than this or infinity, then the fuse is blown.
What happens if Mega fuse blows?
If a MEGA fuse blew, the car likely would not operate at all because these fuses protect critical, high current circuits, ones important to keeping the car’s electrical system operating. If a fuse (of any type) fails, that causes the circuit to instantly open and then no power flows.
What would cause a mega fuse to keep blowing?
Blown mega fuse is a dead short or crossed wires. Could have the cables crossed, internal short on the alternator or starter but if its blowing that as soon as you touch the cables it’s a big short.
What fuse will keep a car from starting?
In short, a fuel pump fuse is the quickest way to disable the vehicle from starting. Other vital fuses are coil packs and electrical control units. These fuses prevent the car from starting until they are back to their respective places. But it can be challenging to prevent a disabled car from being towed.
Do Mega fuses go bad?
What happens if alternator fuse is bad?
Dead Battery If the alternator’s fuse or fusible link is blown, the alternator will not be able to charge the battery. The battery then doesn’t store enough power for starting the car or keeping it running.
What happens when a fuse blows in a car?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won’t start.
Can a bad fuse drain a car battery?
Even while your car is off, your battery provides power to things like the clock, the radio, and the alarm system. These things shouldn’t have a major impact on your battery. What may drain a car battery when it’s off are things such as interior lights, door lights, or even bad relays.
