Boat electrical work

[Ray]

I had electrical issues on my boat too. Nothing works but the bilge pump. It happened yesterday afternoon. The GPS/dept finder screen froze up. I couldn't turn it off, so I removed it from the dash. Then I couldn't get it to turn on again.
Then I couldn't get the trim tabs to work. Every time I hit the trim tab buttons, all the dash light came on.

But the boat is still under warranty. Thank goodness.
