I am referring to the power circuit. The existing AWG 16 feeds the old chartplotter, Tridata and wind displays with the Autopilot display feeding from the S2 controller box. The yellow data wire and ground run between all 3 RM displays. Now the Garmin which draw 3.2 amps has it own Anchor boat cable of AWG 16 tinned stranded. I will parallel the 3rd wire in the sheath. Thwe voltage drop is still about 1 volt. The spec calls for AWG 14 for extended runs.
