Hi, This is my first post and thank you for all the information out there. I wondered if anyone had noticed a small continuous current draw on the MK PD even when the foot controll is not pluged in? This flow is .023 AMP on my multimeter. It's enough to make a spark when connecting the battery leads. I called tech support at MK and he informed me this was normal due to the printed circuit board. I know it's not much but, it just seems odd that the motor would draw current even with out being used. Any ideas?
