Why does my light bar keep blowing fuses?
Why can a light bar fuse blow? A light bar fuse will blow when something in the light bar electrical wiring is faulty.
Why do I have a loose fuse holder?
Loose connections are common with poor quality fuse holders. Because they don’t make adequate contact with the fuse, they can allow dirt and dust to get in between the contact points – resulting in voltage drop. Heating in an electrical circuit is always caused by current flowing through a resistance.
Is there a problem with my Fuse Box?
One of the first symptoms of a problem with the fuse box is fuses blowing frequently. If the fuse box has any sort of wiring issues, such as a short, it may cause the fuses to blow frequently.
What causes an inline fuse holder to melt?
Heating in an electrical circuit is always caused by current flowing through a resistance. If there is significant resistance in the contact between fuse and fuse holder, a current well below the fuse rating can cause enough heat to melt an inline fuse holder. Note, this heating of the electrical fuse may not always be immediate.
What should I do if my amp fuses are blown?
Not many amplifiers will illuminate the protection light when the fuses are blown but a few will so you need to check this. If the fuse holders are melted, you need to have the amp checked by a technician to determine why they melted and to determine if the fuse holders are usable.

Why does my Light Fuse keep blowing off?
If the fuse is still blowing there is almost certainly a wiring fault on that circuit and an electrician is needed. If changing the bulbs in the faulty circuit cures the problem throw the old bulbs away – one of them has an internal short.
How much power can an in line fuse holder hold?
Enough to feel quite warm or hot. Now if the current is higher or the fuse contacts are higher in resistance then the power and fuse holder temperature can increase dramatically. A couple more amps and another 10 miiliohms of contact/fuse resistance (don’t forget that fuse resistance changes with temperature) will increase the power to 4.5W.
