How to troubleshoot common underwater connector issues?

Quick Answer

Common issues and solutions: (1) Intermittent connection – check for corrosion or loose contacts, (2) Leakage – inspect O-rings and torque, (3) High resistance – clean contacts and re-terminate, (4) Physical damage – replace connector. Always disconnect power before troubleshooting.
