Why do the positive and negative wires spark when touched?
When the wires are connected, it forms a short circuit, with extremely high amounts of current flowing through the wire due to the negligible resistance of wires. This causes sparks.
What would cause a ground wire to spark?
Most likely though, since the ground doesn't blow the breaker on it's own, the junction box is powered somehow. In one way or another, power is feeding through that box. It could be from the sheathing of the BX or any stripped or loose hot wire touching any of the system.
What causes battery arcing?
When additional fuses are included in the electric system, the battery starts malfunctioning and transfers excessive current. This causes fuses to melt and wires connected to it start arcing.

Will a battery terminal shock you?
Although you can't be electrocuted by simply touching the terminals of a regular car battery, due to the low voltage, you can receive a nasty shock from other components of a traditional automotive electrical system.
Why do you connect the positive terminal first?
Connect positive first, negative having less potential won't arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.
Which battery terminal do I connect first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
What happens if you connect a negative battery terminal to a positive?
If the positives and negatives are switched, the battery will try to compensate and make the negative 12 volts into a positive charge resulting in a huge surge of power and an enormous amount of heat to be produced.
What happens if a golf cart battery leaks?
If you have a leaking battery, then corrosion is inevitable and it will affect the battery terminals. This will eventually seep into the posts and melt them. Check out for a battery terminal protector from your golf cart parts store. This is usually available in the form of a spray.
Why does my golf cart battery melt?
The main reason why golf cart battery cables will melt is because of too much current passing through the jumper cable; resulting in overheating and melting. A poor contact connection or a missing ground strap between the chassis and the engine may also result in the melting of your golf cart battery cables. Alternatively, corrosion of either of ...
What causes a cable to overheat?
Excessive internal resistance. The internal resistance of the cables used to connect to the terminals may be very high, leading to overheating followed by melting. Check the resistance of the cables with the help of an ohmmeter. The resistance between both ends should ideally be zero or as negligible as possible.
What causes a battery to melt down?
A stalled motor can cause the terminals of a battery to have a meltdown. It happens when a motor receives enough power to get started but it fails to turn. This is common when the cart is over a steep incline or a curb. It may be time to charge your battery and replace the melted terminals with new ones.
Why do the bolts on my cable terminals melt?
The bolts on the terminals often melt because of excess heat and even tend to break. When this happens, the terminals are also affected. One main reason for the heat generation is a corroded connection. This corrosion increases the cable resistance and thereby the heat, which leads to melting.
What happens when two cables touch each other?
Short circuit or fused connection. Two cable ends that accidentally happen to touch each other can result in a short circuit or a fused connection. Remove the shorted cables and use new cables to reestablish the proper connection between the terminals.
