Hey guys, I took out my old Lowrance Gen 2’s and am trying to put in my new Garmins. At first I had no power at the old leads that the 9’s were connected to and the radio wouldn’t work either, then I switched some wires around on the terminal block. When I turned on the master switch two of the 3 garmins turned on without using the power button. The third turned on when I pushed the power button. I switched some things again and they were back to no power. I checked all the grounds they all seem connected. I have a ‘13 Bass Cat.
Thanks for any insight.
