Blue corrosion on DF6 plug

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Bill,

Raymarine does not recommend any specific contact cleaner for the specified purpose. Should the display remain connected to the power/transducer cable throughout its life, then the seal should prevent any corrosion to the plug's female pins. However, should the display be regularly disconnected to the power/transducer cable, then it would be recommended that dielectric compound (ex. Dow Corning DC4) be applied to the pins of the power/transducer cable and that a power/transducer cable boot be installed when not the display will be unplugged from the cable. Should your Dragonfly display not have been supplied with a power/transducer cable plug boot, then please respond accordingly.
