I have a newer triton 2-years old with a ghost trolling motor that came with two Elite 9 Lowrance units installed at the factory. One on the bow and the other on the console. I have active target 1 installed and I just recently added a Elite 7 to the bow . My question should my new addition of the Elite 7 on the bow should it be connected to the Nema backbone . It is connected with an either net wire to the network but I'm have some problems with my Ghost Trolling motor just curious thanks
