    Hello,

    New to the 400. Why does the magneti marelli aec 104 bk whine when key is in the accessory position? Happens right before start engagement. The pitch changes frequency if you turn on an the fan or radio. Is this normal ? If not normal who repairs these?

    Thanks

    Pretty sure this is normal operation, mine does it too, no problems.
    I think the worrying begins when it stops whining.
