i am using 4 dc motors and i want to put the .01uF capacitors to eliminate noise how do i have to put the capacitor from Y to cap to motor on each one of them or on the + and - of the motor but there is a y in the negative to go reverse already.

sorry about the drawing im just trying to draw it fast.

    Each motor needs 3 non-polarized caps for the traditional delta filter. See sketch, one cap bridges two motor terminals (+ and·-·as marked) and each terminal has another cap going to the metal motor case, just scuff the surface with sandpaper and solder it quickly with a BIG (200 watts or more) Weller soldering iron.

    Check out http://www.kronosrobotics.com/an101/DAN101.shtml
    but you'll need to add the 3 caps per motor per my previous diagram.
