Put the new boat in the water tonight for a quick learning session on the electronics.  I assume everything was installed correct.  the marina owner was The previous owner.  I immediately flipped to the structure screen.... black.  I'm such a dang rookie to electronics I don't even know where to begin.  So opened the manual.  Confused I turned to I google.   More confused lol.  

 

I just emailed the sales person I worked with but I can't wait till tomorrow lol.

 

Any words of wisdom on what I'm doing wrong?

 

I have a little more information about this.  The graph is hooked to an less-1 via a Ethernet cable.  The Acc rocker is in the one position (I think it might be run off that?).  The settings on the graph have the structure scan on.  Still black.  Transducer issue?  Maybe a cover that I failed to take off?

go to you-tube. they have tutorials on everything Lowrance.

I'm leaning a bit more every time I mess with it.  Spoke to the marina I purchased from.  Sounds like I might have a compatibility issue with the lss-1 and the gen 3 Hds7.  Looks like I have to by pass the box and hook the transducer directly to the unit.

 

Before. Start pulling wires I will hook the gen 2 unit up at the bow with the current connections.  Theoretically that should work... I think.
