Stuck Electrical Connector

Logic,

The socket is designed to be unlocked, not locked, when the locking collar's tabs have been rotated into the 12 o'clock and 6 o'clock positions. As you have indicated, the locking collar will rotate clockwise two clicks such that the locking collar's tab is slightly less advanced than the 3 o'clock position. This is the locked position. The plug's o-ring forms a fairly tight fit to the power/transducer socket and as such, some force may be required to remove the plug. Should salt crystals have formed around the plug's o-ring, then this may cause additional resistance when removing the plug. Flushing the area with fresh water may dissolve build-up salt crystals. Should the locking collar be oriented as specified within my initial response, then plug may be pulled from the socket. However, should the locking collar have been over-rotated during use, then damage to the socket may prevent the plug from being removed, necessitating the action specified within my initial response.
