Quoted from Gambeno:
Thanks for the reply and help. I went into test mode and its a no go for both, they didnt respond at all to moving. I also check the board and everything seems to be connected and the board is getting the 48V. Not sure what to check next. It's odd that both do not work. I'm assuming this is the test mode to check the motor? [quoted image]
Yeah that's the right test. I'd follow all the cables coming off the 9c node board back to where they came from and re-plug them at the source side. Did you re-plug all the cables or just look at them? Unplugging and re-plugging may show up loose wires that aren't properly clicked into their connector, but look okay.
Check Node board 9b to make sure that the connector at CN2 on it is completely plugged in. That's the one that sends serial commands to the 9C node board.
Here's what the connectors look like on my node 9c. Compare with yours to make sure everything's plugged the right way and the wire colors are right...

Also, if you have a Jurassic Park Prem/LE you can "borrow" the same board off that machine to test it in your Iron Maiden. It's on the back panel of JP2.
