The resistance at the screw terminals came out to 1.4 ohms. When I plug the power I do see the Arduino light come on, then after about 5 seconds I see the light on the mosfet turn on. I measured the voltage on the mosfet and it read .011 as soon as I plugged it in, then when the light came on, the voltage went up to .333 volts. I had the meter on auto range, so I hope that range is correct. one thing I forgot to mention on my first post is that when I had finished assembling everything and was testing it, there was a small short. One wire strand (positive) from the 12v power supply made contact with the negative wire and made a clicking noise. after that all the LEDs turned off and motor did not turned. after disconnecting the power, and fixing the cable, I plugged it back in and everything worked again. not sure if that burnt something on the board. I didn't put the smart motor before that, so i'm not sure if it worked before that wire short.

i'm editing this post because when I touch the mosfet with just one lead from the multimeter I get around 4.2 volts.
