    hi,
    I want my car stereo can power when the engine start, not when the panel lights turned-on.

    in short I want the car stereo power when there is an engine acceleration.

    with that wiring I can also top other wires for example my dc electric fan.

    what are your ideas? suggestions?

    hi,

    So, there is really a way to make this direct top connection, rather buying a delay relay(1 min) from an electronics store.

    thanks.

    I got someone to build a circuit that sensed difference between - resting battery voltage and 14V when charging .
    Has bonus , if alternator loses the battle , amplifier loads etc get removed ! (Get an ignition /side lights sense cables included in design -if overrides are needed ) Auto/Manual/Off ...
    Not as easy to sense the old Ignition/charging lamp circuit any more!
    (on Modern ECU/BCU-Digi Dash-board cars)
