Hello!
I hope you can help me..I have slightly cleaned the contacts of the 4 relays in the black relay module of my Mpi with some very fine grinding paper, because over the years they got very black and I am trying to sort out some electrical problems at the moment. Are there any negative aspects after doing this? I have heard many people are doing this to get the box working again..
