More often than not, the problems with the magnetoloire are related to the cigarette lighter that was burned. The point is that the Duster unit has a special design, and a short circuit that burns the fuse is activated with active use. The same fuse is the responsibility of the magnet. This does not disable the magnet completely. She's starting to work incorrectly.
To restore the operation of the magnetola, you need to disengage the cigarette lighter and replace F38 15A fuse. To avoid a short circuit, it is necessary to ensure that the connector pins are parallel to the ground.
