We have hooked up our fisher prices under no load and we did not notice any arcing at all. I dont think that you should be noticing arcing unless something is wrong. If I get a chance I will check the motors with a load in the morning to see if ours arc. Good luck with motor troubles (my team knows how that is right now, our drill motors have a really bad wobble when the left hand threaded bolt is screwed into the coupler and gearbox).
