Why does my amplifier keeps blowing fuses?
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.
Why does radio fuse keep blowing?
A fuse blows because of a couple of reasons. It happens if the fuse used is lower than the rating for the device. Installing a higher capacity fuse may allow the blower to continue operating, but the higher current load will cause the wire to heat up before the fuse blows.
What causes an amp to keep blowing fuses?
Poor ground connections are a common cause of blown fuses and destroyed amplifiers, so double check all ground connections to make sure they are secure. Check for internal defects in the amp. If despite your best efforts, the amp is still blowing fuses, it is more than likely that the problem involves either an internal fault, or bad speakers.
When to replace a fuse in an amp?
When an amp blows a fuse (or fuses, for amps with multiple fuses), you should replace the blown fuse with a fuse rated for less current. Let’s take an amp that has two 30 amp fuses. If the OEM recommended fuses blow, there is likely a serious problem.
Why does my DBlock amplifier keep blowing fuses?
If the main fuse isn’t blowing but one of the fuses in the dblock is blowing, that tells you that there is a problem beyond the distribution block. It could be that the wire feeding the amplifier is shorted to ground or there is something wrong with the amplifier. If you can see the entire length of the wire, make sure the insulation is intact.
What causes an amplifier to go into protection mode?
If the amp powers up normally and plays at relatively low volume, the amplifier is likely in good working order and you can replace the temporary fuses with the OEM recommended fuses. Blown output transistors are the most common failure in amplifiers and are also the most common cause of an amplifier going into protection mode.
