[CA] [CA11] Speed Transducer Wire Colours

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Randy,

The colors indicated for the wire colors of instrument speed/temp transducers within the ST60 instrument manual, back side of the instrument, and inside of the iTC-5 have remained constant for at least the last twenty years. Is it possible that the boat builder or installer extended the leads of the transducer cable?. If so, it may be necessary to trace the cable back to the splice. Alternatively, should you know which pins of the ST60 instrument that the leads of the extended cable had been connected to, then you need simply connect them to the corresponding color coded Speed/Temp pins of the iTC-5.
