Course computer S3G AST - Eder - 04-23-17 11:29 AM
I am buying back up parts for my Raymarine auto pilot for a Pacific crossing. The course computer is a S3G AST...I found one but the owner claims it requires 24v input power...are these not duel voltage? If not is there a way to make the 24v unit a suitable replacement? Thanks

Welcome to the Raymarine Forum Eder,
Only one version of the S3G was produced. It was designed to be powered from a 12 or 24 VDC circuit. When interfaced to a 24 VDC system, a 24 VDC drive unit had to be mated to the S3G.
