    Not sure where to post this.
    2017 mercury 150 4 stroke.
    With everything off drawing 3.5 amps.
    Draining battery fast.
    Anyone have a guess on where to start looking.
    It’s somewhere in the motor/ motor control side of the world.

    Disconnect the wires at the alternator including the big wire,if that kills the drain the rectifier is shot.
    It could be the main relay too.
