MOOG 15 emvelope problems

Finally I got yesterday my Moog keyboard.
Today when I have start to patch the 15, I have realize that the envelopes are not working (?).
After making some test : I have discover that ONLY the SECOND row of the controller outputs is working fine ( the 1º and 3º row not!!!).
Some suggestions before looking to found a tech… (Grrrrrrr!!!).
I will apreciate your comments
Kind regards

Check your power connections to the 911’s and also check the Gate connections both from your keyboard and your 911’s …try shorting the Gate connections at the 911 with a screwdriver to make sure everything there is correct.
If they don’t trigger it will be a power connection problem.
