Yes I am running a capacitor. Thank you, will try another capacitor. However, when the red/green lights are flashing the power is still there but accelertion to top speed is very slightly slower and less smooth (just as the system runs when no sensor wire is installed). Another way I have troubleshot the problem is...when the red/green lights are not flashing (normal operation), and I swap two of the phase wires on the motor, the motor will not do anything, or it stalls because the sensor system and the wire phases have conflicting signals. But when those lights are flashing, and I swap the motor wires, the motor runs to top speed. This indicates to me that its a sensor issue, not a power issue. Hmmm.....
