Looks like my X-treme XB-600 hub motor may have finally died. I'm not getting continuity between the green phase wire and the other two phase wires. Though, I haven't opened up the motor yet, the break is either in the green phase wire leading to the motor windings, or the motor windings themselves. If it turns out to be the windings, anyone have a replacement motor suggestion (compatible with the X-treme XB-600 frame)?
