thanks, that has given me lots of ideas. I found the crosstalk that was causing the EMI too, and it goes directly which what you are saying. So for planning the new control box, I will isolate the low, mid, and high voltage wires to their own areas. I'll also shield them as well. The control box itself I bought to replace this is also shielded too, so anything in the room won't interfere too. I'm not taking chances this time. I plan on making interconnects for everything outside the box too, so I won't have wires just going through a hole, or several holes, including the open side as my current scheme is.
Thanks for your help.
