I had the same situation with my A50 so went to the boat and did a continuity check between ship ground and the cable output and was surprised to find that the Ground and Positive were positioned inversely to my expectations so don't take any chances. My A50 is working fine at home. Ask Raymarine on their Web site. I find them very helpful.

I need to power it up to archive my routes and waypoints however the wiring harness is at the boat (2.5 hours away). The + and - power pins on the connector are obvious, but does anyone know which is which, I am afraid of reversing polarity and damaging the unit. I checked the manual and searched online but came up with nothing. Also checked resistance between pins and casing to ID the negative pin. However probably due to capacitance on the board, there are funky resistance readings and its hard to tell which pin is ground.
