After carefully reading your sentence I believe I understand that you have no power going to the red and black wires. I assume you are talking about the large black and red wires. I also assume you have a battery hooked up and if you are not seeing power then the battery is not producing voltage, or you have a main fuse blown or circuit breaker tripped. even with the power the large red and black wires should have voltage.
Also is it the brushless motor controller like the last controller on this page
