Quoted from Krupps4:That was the problem! Thanks Dawgs. Thanks everyone!
Quoted from dawgs:Check the connector at J16 in the back box. The ground wire on the piggeyback on mine was in the wrong place. I ended up not using the piggeyback and grounded it elsewhere.
I had the same issue. I have the 2018 Pro LED version.
The shaker ground wire is already in the front of the cabinet; directions must have been for a different version that doesn't have the shaker ground wire already.
My kit also came with the Revision B board and the filter board so it was very confusing when the directions did not refer to either board and following the directions resulted in the shaker not working.
Thanks dawgs for posting the solution. The shaker on MET is a huge upgrade. Very well integrated and well worth the hastle/money!
