(Concerning MK power drives). Does the power board switch pwm simultaneously with the power transfer relay or is pwm delayed a few milliseconds so to make a no load power switch to the motor? I get a little impulse noise when the relay "clicks" on. I can scope it out, just was hoping you know.

I ordered that faraday cage today. I guess I weill "guess" as to which end to ground or not ground or no ground at all. Probably ground the cage at the power board first since it is the signal originator. "Justa Swagging".
