Koolaid, there are 4 solder pads, they are mared m1, b-, m2, m-. The m- is a 2 wire connection. The b- goes to the switch. I'm just guessing, but if you have 2 wires off, and both of the motors do not turn, that is the connection that is off. Are the 2 wires soldered together? That would be a dead giveaway. Good luck, Tim

I recieved my Picco Z today!! This thing is fun. I have a couple of questions, of course, but will ask them on the appropriate forum. Tim

PS. If everything silverlit makes is this good, I hope Chinese Government doesn't enlist these guys into their Air Force. HA HA. Tim
