Do the following:
switch off the A-100.
Remove all conections. Definitely remove the MCV24.
Turn all pots of the A-141 to zero (7 o'clock position)
Switch on the A-100
-> Does the LED of the A-141 glow?
    If no: The A-141 itself works fine. Continue below at XXX
    If yes: plugin a cable into the Gate socket (other end
            hanging loose)
            -> Does the LED still glow?
               If yes: A-141 is broken
               If no: the A-141 receives some gatesignale via the
                      bus check out where it is coming from.
                      Connect the cable to rectangle out of an LFO. The
                      LED should blink short in the tempo of the LFO.
    XXX: If LED doe not glow at first check:
    turn Sustain-Pot (NOT the CV-Sustain!) fully clockwise.
    -> Does the LED glow now?
       If no: A-141 is good, but you had some troubles in gate wiring
              with your MCV24.
       If yes: plugin a cable into the Gate socket (other end
               hanging loose)
            -> Does the LED still glow?
               If yes: A-141 is broken
               If no: the A-141 receives some gatesignale via the
                      bus check out where it is coming from.
                      Connect the cable to rectangle out of an LFO. The
                      LED should blink short in the tempo of the LFO.
