IF THE FUSE YOU ARE PLACING IS THE SAME TYPE AS THE ORIGINAL YOUR AMP HAS A PROBLEM WHAT YOU MUST DO IS TO SLIGHTY INCREASE FUSE BY 100 MAMPS PER TIME IF IT IS IN THE TRANSFORMER CIRCUIT YOU CAN INCRESE IT BY 2 AMP MAX IF IT IS IN THE MOSFETS CIRCUIT YOU CAN INCRESE IT BY A MAXIMUM OF 500MAMP LET ME KNOW THE RESULTS

If you are not using the 12v trigger between pre-amp and power amp make sure that the trigger switch on the rear of the RB-1070 is set to off

SOURCE: KEEPS BLOWING SOUND FUSE

When you refer to the "sound fuses" are you referring to the speaker protection fuses or the power supply fuses?

SOURCE: gem sound dj amp blows fuses on the right side

There is a problem with the output section. The most common cause is shorted output transistors. This unit should go in for service. Without seeing the unit and testing it, I can't indicate all of the defective parts. You should expect a parts cost between $25-$45.

SOURCE: I have no sound coming from my amp a rotel rb 981

it is never advised to change wires while the amp is switched on. you may have blown your diodes on your post amp then you have a problem.
have you tried other speakers tested your speaker on another system to rule them out as OK?
if you open the case be careful not to touch any large capacitor as they may still be chared and can give you a nasty belt.
any fuses should be easy to find and to see if they are blown. ensure you get the same rate fuse when you replace. if you see any charing of diodes then i think repair may be costly. good luck.

SOURCE: the two 5 amp fuse inside the amplifier keeps blowing

Hi,

That must be the inrush current.
Maybe you are using the wrong fuses.
Please check if those are fast or slow types.
You need slow types.

Good luck,
Gerard

I am install 20 amp fuse and it still blows


Sounds like you have a direct short somewhere. Closely examine your wiring harness for bare wires and pay attention to anywhere wiring is running on or through hot or sharp areas. Does the fuse blow as soon as you plug it in, or only when you turn the key?

I'm fues to my fan keeps going out on my 2006 P.T


More than likely you have an internal fault either in the fan itself or the thermostat that activates it.

For a fuse to blow it has to have a lot higher than normal current draw through it, which is normally refered to as a short. If the fuse blows almost immediately then I would suggest you unplug the fan, and see if the fuse blows with just the thermostat in the circuit. If it blows - replace the thermostat control. If it doesn't blow, plug in the fan and watch it. If it trys to start and then blows the fuse, replace the fan motor.

Fues blown in xpower inverter 1750 plus


These fuse are often intend to protect voltage inversion. (reverse voltage)
So, if the eight fuse are blown, then maybe the voltage red and black wire were not connected to the correct polarity.

then again, even if these fuse are intend to be use as reverse protection, it may occure that transformer short out, transistor short out and many other short circuit inside the inverter as occure.

So replacing all eight fuse might not restore the unit function, they may even blow again.
Also, reversing polarity that cause the fuse to blow might have damage the transistor stage.

I am still, investigating few other problem with those unit.
I don't have all answer yet.
