How do you fix an amp that keeps blowing fuses?
Replace the blown fuse with everything turned off. If the fuse blows with everything turned off, there is probably a short between that fuse and the rest of the system. Replace the fuse again with the amplifier disconnected. If the fuse still blows, there is a short somewhere in the wiring.
Why does my guitar amp keep blowing fuses?
If your amp blows a fuse, it’s almost always for a reason, so make sure you get somebody to investigate. The most likely reason is a dead power valve – a 6L6, EL34, EL84 or 6V6. Most valve amps with EL34s or 6L6s must be re-biased when (see bias page) you change the tubes.
How do I know if I blew a fuse in my amp?
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
Can I put bigger fuses in my amp?
In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current.
Why do my subs keep blowing?
Subwoofers are most commonly blown by supplying too much signal to the car audio amplifier. Too much signal results in a “clipping” which is when audio signals voltages reach amplifier’s power supply voltages. The result is a “clipped” signal and this can damage the amplifier and subwoofer.
Can I replace a 15 amp fuse with a 20-amp fuse?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
What happens if you use a higher amp fuse?
If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.
