Power Adapter Fuse

The Boss Audio ATV85B comes with a 15 amp fuse. If you are blowing the fuse after about 3 seconds, it is likely that you have wired the new power plug incorrectly. The power plug should be wired in series with the fuse, and the fuse should be in the line that goes to the unit. If the fuse is in the line that goes to the power source, it will blow every time you turn on the unit.

To check the wiring, you can use a multimeter to measure the resistance between the power source and the unit. The resistance should be very low, typically less than 1 ohm. If the resistance is high, or if there is no continuity, then the wiring is incorrect.

Once you have checked the wiring, you can try replacing the fuse. If the fuse blows again, then you may need to replace the unit.

Here are the steps on how to replace the fuse:

Disconnect the power from the unit.

Locate the fuse. It is typically a small, cylindrical component with two wires attached to it.

Remove the fuse by carefully pulling it out of its socket.

Replace the fuse with a new one that is the same size and amperage.

Reconnect the power to the unit.

The fuse size for the Boss Audio ATV85B is 15 amps. You can purchase a replacement fuse at most electronics stores.

Here are some tips for preventing the fuse from blowing again:

Make sure that the wiring is correct.

Use a high-quality fuse.

Do not overload the unit.

If you are still having problems after replacing the fuse, then you may need to contact Boss Audio customer support for assistance.
