Well yesterday sucked.. I somehow fried the motherboard on the motor box. So I cut the wire leading from the box to the outlet directly into the motor eliminating speed control and display to just have power only.. my motor started to overheat so I unplugged it and assumed that the motor was getting too much voltage from the original 220 plug that came with it so I ended up cutting off that plug and splicing in a 110 extension chord. Seems to be running fine now.. Anyone else ave this problem?
