1. Make sure connection is clean and dry, use dielectric grease don't over due it.
2. Always connect fishfinder first.
3. Connect battery
4. Disconnect battery.
5. Disconnect plug/s from fishfinder.

Don't ever let your connections come in contact with seawater with the battery connected! If you do rinse it immediately with fresh water.

All of the above along with a protection plan
