Power issue

Can anyone tell me why my graphs were turning off in rough water today? They also blink on and off when I start my motor. It’s started early this morning and seemed to go away as the day went on.

Bad connection or loose ground.

Had old HB on big water had internal problem would turn off when it got bad.

This. Take some contact cleaner and spray the connections. Then take a dab of dielectric grease and put on all connections... battery terminals, transducer connections, head unit power etc.

The blinking off when starting the outboard is from voltage dropping below minimum required to operate the unit. Check ALL connections and have the battery checked.

I had issues with mine and couldn't find any bad connections. I pulled new wires and it solved the problem. I had a weak spot in my wires that I couldn't even see.
