First I am going to have to assume that you are talking about a 1997 National RV Sea Breeze Class A Motorhome. For some reason National RV also manufactured a 5th Wheel Trailer Called the Sea Breeze in 1997.
If your Sea Breeze is equipped with a battery cut off switch you will find it as you enter your Motorhome you should see a series of switches. The switches operate your outside porch light, one of your interior lights, etc. and one of those switches should be the battery cutoff switch.
