After contact with a dock, my GHC 20 (autopilot) stopped working. It does not turn on as if there is no power. I have checked all fuses and connections with electronics at the helm. I also removed the refrigerator and checked the NEMA backbone behind the refrigerator. The connections seem to be secure. Additionally, I checked the CCU and ECU. There are no active lights on the ECU. The fuses in the port sub deck locker seem to be good. Any idea where I can check to pinpoint the electrical problem?

I have removed the cable attached to the GHC20 which shows a five-pin connector. I will retest that connection since I recently found the 5-pin connection schematic. Where does the power for the autopilot system come from?

Can you assist me in getting my system running again?
