[DG] [DG] p70s Not Reading ST50 & ST60 Instruments

[Ramvet]

Hey Derek,
I think we are getting closer. I see what you mean, not connecting the red wire in the connection from ST50 instruments to the converter. Cut that today (must be part of the problem) & lost power to the ST50 group. And yes, going from the Speed Gauge to the SeaTalk converter, I did connect yellow to yellow and bare wire to black in the Spur Cable (K location in included drawing).

So it seems to me that I should now supply power directly to the ST50 instrument cluster as shown in the included detailed drawing here. If that is correct, do I join red to red and black to bare wire at the question mark in the drawing at the Depth Gauge? Or red to red and black to yellow?

Thanks again! You have been super helpful!
