How to prevent amplifier fuse from blowing during power switch on?

The idea is actually quite simple. To prevent the amplifier fuse from blowing we simply need to ensure that the amplifier input power is applied with a soft-start AC input. To implement this a small delay ON timer can be employed.

What does it mean when a fuse is blown?

Yet people commonly use the expression “blown fuse” to describe just about any unexpected electricity-related occurrence, especially one involving a loss of power. A “blown fuse” can mean many different things–several of which have little to do with actual fuses.

Why does my ECM 1 fuse keep blowing?

If the wires leading to the O2 sensor rub against the exhaust, it creates a ground; once the O2 sensor is grounded, the fuse to the ECM 1 blows. The O2 sensor must be installed in a different place to ensure the wires do not short-circuit.

What causes a fuel pump fuse to blow?

When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow. Replacing the fuel pump should correct this problem. The ECM 1 operates via voltage sent from the battery.

Where is the fuse on a Harley Davidson Softail?

Looking inside the fuse box, you’ll see a 40 amp fuse. This is the main fuse protecting the circuit between battery positive and the starter motor. There should be 12 volts on both sides of this fuse with the ignition on. Touch the positive test lead to the fuse blade and the other to a good ground. 12 volts should display on your meter.
