Why is my fuse sparking?
Usually, a circuit breaker sparks when turned on because it can't receive the right electrical flow through the whole circuit. It can be because the contacts inside the breaker aren't making optimal contact with the metal bars on the panel's busbar or there's a damaged wire somewhere in your circuit.
How do you fix a fuse that keeps popping?

Why does my fuse keep popping?
A short circuit happens when a hot or active electrical wire and a neutral wire touch, causing a large amount of current to flow and overload the circuit. A short circuit should always cause a breaker to trip or a fuse to blow and may also cause sparks, popping sounds, or smoke.
Why would a fuse catch fire?
Heat can be generated wherever connections are loose. When connections are not firmly attached, the electricity must force its way through the weak connection causing that area to get hot (see gfci, fuses, circuits, wiring, breakers, overloading, burning wires for more info).
Whats a dead short?
A dead short is an electrical circuit that results in current flowing along an unintended path with no resistance or impedance. This results in an excessive current flowing through the circuit, which can damage equipment or cause electrical shocks to those nearby.
When should a breaker be reset?
A circuit breaker does the same thing a fuse does, but, unlike a fuse, a circuit breaker does not need to be replaced to be reset, unless there has been a high-current short circuit or an event such as a lightning strike that may have damaged the circuit breaker.
What noise does a fuse make?
A loose connection, or even a minor loss of the integrity of your fuse box connections, can cause the electrical system to 'arc', which can lead to a buzzing or humming noise. The fuse box humming noise actually originates from the arc of electricity between the circuit breaker contacts and the bus bar within the box.
Why does my running light fuse keep blowing?
If a wire going to any of the running lights is exposed and touching metal it will cause a short that could blow the fuse. The other possibility is that if you added any lights to the trailer that use the running light circuit the extra power draw could be too much for the tow package wiring.
