My detachable Sony car stereo died suddenly after a kid tried the max volume. No light. Fuse problem? Thanks.?

Question

The fuse was fine, according to my mechanic. Car stereo has no power. Amplifier problem? If I take out the unit, do I need to disconnect battery?

Answer 1

You probably blew the fuse in the vehicle fuse box that supplies constant power to the radio. This fuse may not be labelled as a radio fuse, so it might take a little work to find it. Check and see if any other constant power devices aren't working; ie, cigarette lighter, dome light, door chime, locks.

Many vehicles have a fuse box under the hood as well as one in the passenger compartment; it's not unusual for the radio's constant power fuse to be in the under-hood fuse box.

There's also a fuse at the back of the radio, accessable by removing the wiring plug; it's possible, but less likely, that the fuse there is blown.

Answer 2

It's the fuse for the interior lights etc. If it blows again then most likely the radio is done for.

Answer 3

Check your ground wire if its not a fuse.
