I have not used Easy C, but here are my thoughts.
Are they connected to the correct PWMs?
Are supposed to be connected to Victors or Spikes?
Do you have the controller in the correct port on the OI?
Are they faulty wires you are using(bad PWM cable, shorted wire)?
Power connections are fully made and have contact?
Have a breaker and that it is not tripped?
Those are more of hardware issues and my thoughts. Hope it helps
