Syma X8HG Motor Problem

Hello everyone. This is my first post. I am a newcomer to the world of quads. My son got a Sharper Image X7 quad from his Opa for Christmas and we both have been bitten by the bug. I bought a Syma X5HC and then decided to step up to a Syma X8HG to get better video. I have been satisfied with the quad, other that having to pay the Feds a 5 dollar tax to fly the darn thing and having to call the local GA airport anytime I want to fly it. Anyway, I bought the upgrade motors from NightLion off of Amazon and finally got around to upgrading. When I got everything back together one of the motors did not function. I removed the motor from the quad to ensure that it wasn't just a gear mesh issue and the motor doesn't function at all. OK, I then plugged one of the original motors and that didn't work, along with the other three. Here's where I get confused. I flipped the quad over and spun it up while checking the connector pins on the quad. I get battery voltage to the pins. I checked another motor that was working and got similar voltage. What gives? It doesn't appear that the connector is moving down in the quad. I appreciate the advice in advance. Looking forward to what you guys have to say.

Did some additional testing after taking the quad apart. I get voltage at the pins, top of the connector, and at the output on the board with no motor connected. When I connect a motor, and I tried several motors, I lose voltage at the same tesf points. I'm guessing it's the ESC but not 100 percent sure. I ordered a new board and will replace that. I did try the motor in question on another input and it works fine with no issues. Am I on the right track? Thanks again folks

Keith.......did you go thru the complete binding process??? Including whatever you call it......resetting the gyros??? I've noticed similar problems when I've had an exceptionally hard landing(read "crash") and that I will have to shut everything down for a few minutes and then go thru the binding and resetting the gyros procedures and then I'm fine..........
