I'm about to install a Raymarine fish finder on Cheeky Monkey and upon reviewing the manuals that came with it there are three wires for the power. There are the usual positive and negative, but it also has an "RF ground".
Does anyone have advice on where this is connected? I guess I could just trace back the VHF radio wires and see where that one leads... but then again the PO who installed it might not have known all that much about it either. Larry Robertie Cheeky Monkey Boston, MA
