This is due to spikes of high voltage jumping through the system which in-turn blow the bulb filaments and/or headlight fuses. You can perform a simple test to check if the voltage regulator is faulty, however you'll need another person to help you rev the engine whilst you take a multimeter reading.
How do you fix a fuse that keeps blowing?

What would cause a fuse to keep blowing?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. ... A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.
Why did my headlight fuse melt?
Cause: If the fuse itself has not blown, but the fuse holder melted, it indicates that the fuse holder was making poor contact with the fuse. ... The simple answer is: if the fuse holder melted, it is due to a lost connection, not the power wires drawing too much current .
Why does my 10 amp fuse keep blowing?
Check what devices or lights are on that circuit, as it may be the case that a new amplifier pulls too much power , causing the fuse to blow. ... The number embossed on the fuse, such as 5, 10 or 15, indicates how many amps may be pulled through the fuse before it blows. Each wire in a car has a specific gauge or thickness.
How do I stop my amp from blowing fuses?
The only fix for this is to have a stereo shop repair the amp , or replace the unit completely. The amp fuse would blow to protect the electrical system of the automobile and prevent further damage or fire. Also, using the wrong size fuse in the amplifier can cause it to blow.
Can a blown fuse cause a fire?
Answer: Absolutely, an outlet that has blown a fuse can start a fire . If the problem was whatever was plugged into it, and that item is no longer there, there should be no problem, but if the problem was within the outlet itself it should be repaired immediately. The time to a fire could be from 2 minutes to 2 years.
What is the most common cause of a blown meter fuse?
The circumstance that will most likely cause a fuse to blow is trying to measure voltage while the multimeter lead is connected to the (amp) function.
Why does my 15 amp fuse keep blowing?
Having too many devices plugged into a circuit is the most common cause of fuses blowing. ... Another potential cause of fuses blowing is a short circuit. When a hot wire touches either the grounding pathway or a neutral wire, it results in the circuit shorting out.
Should fuses get warm?
It's normal for a breaker to feel warm when current is passing through it, but it should never feel hot . If it does, and you're sure it's securely anchored to the panel and the wires are tight, there's probably something wrong with it.
Do fuses generate heat?
Both Polymeric (Positive Temperature Coefficient) PTC and traditional Fuse devices react to heat generated by the excessive current flow in a circuit . A fuse melts open, interrupting the current flow whereas a PTC limits current flow as it rises in temperature, changing from low to high resistance state.
What happens if the battery fuse blows?
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.
Why does my amp keep blowing fuses when I turn it up?
In most cases, an amplifier will blow fuses due to internal damage caused by the way it was installed . ... An amplifier that blows the main power fuse immediately after you turn it on or when the fuse is inserted into the fuse holder is usually damaged in its power supply or output section, and will require serviced.
Can you fix a blown amp?
However, there are a few basic problems that can cause a car's amplifier to sound like it is blown that consumers can fix with limited technical knowledge and no special tools. ... In most cases, car amplifiers are housed in the trunk and can be removed with just a Phillips head screwdriver.
