I'm replacing my radar (and chartplotter) with a Garmin open array version. The install instructions require a ground be installed from the 'radar pedestal to a water ground location'.
I've not heard of 'water' ground before but after looking it up I believe that this would be the negative of the battery. Logic being the negative of the battery is connected to the engine, which is connected to the drive shaft (straight shaft configuration), which is in the water! So connecting to the common ground bus bar in the ER should do it.
Anyone else done this install and is this how you wired to a 'water ground' location?
