BigRrr…no mag feed

Hey lads, just bought a BigRrr mosfet installed it all by the directions, assembled the rifle and went to test and program it all programming works and saved, but doesn’t have any mag feed.
I also don’t have any power going to the terminals when I pull the trigger.
I don’t know what it could be. All answers and advice. Greatly apxpreciated.
Cheers
