Yikes!! hilig ko pa naman i double click yung power window (4) buttons just to be sure kung sagad na yung sara ng bintana, but i'm doing this while the car is running. Am i abusing the battery or the alternator? i'm using a plug-in voltmeter and notice that evertime i doubleclick those power window button, the rating drops from 14.0 to 12.9. Lakas pala kumain ng current ang power windows. Thanks Sir Niky for the diagram illustration.
