Graphs turning on with master

[blue perch]

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.

There is probably a relay somewhere that will power up the circuit the units are on.

Is this a terminal block installed by Basscat, or one that is aftermarket.

Garmins have an Auto on function. Turn power on and they turn on. I have mine set up this way. So check that before you go crazy!

The terminal block was on the boat. I’m guessing it’s original from Bass Cat.

If that's the case, you shouldn't be rearranging the wires on it. These are mainly grounds going to other appliances. The depth finder should be ran on it's "own" circuit and not tapped into existing wiring.

Ok. I ordered a TH Marine hydra for my electronics so I will put the garmins on there.
Thanks for your help. Jesse
