ArcaicArcane has a dandy tutorial about those things here: {

The wiring on the brown one needs checked and probably replaced too.
If you haven't done these things already.

Thanks Joe! Yeah I already tore down the brown controller, cleaned everything including the disks and changed the wiring but I am still not sure I want to trust it.
Since I do have a spare available, I will attach a note to the "bad" one and probably save it for extra carbon disks if I need them. I feel safer going with the other controller.
