What to do if the Fuse Amp LED is ON on my Fusion FM-504?
- IidavisJul 30, 2025
If the Fuse Amp LED is ON in your Fusion Amplifier, it could be due to several reasons. First, the amplifier fuse might be blown, in which case you should replace it with a new fuse of the correct AMP rating. The amplifier may also be overheating; try moving it to a more ventilated location. Additionally, check for shorted speaker wires, ensuring they aren't touching each other or the vehicle's chassis. Finally, there might be an internal malfunction. To check this, disconnect all wires except ground, power, and remote, then turn the amplifier on. If the protection light remains on, it needs professional servicing.
