i got a 2004 cougar with problems. last week i went to the lake fishing and got to where i wanted to fish, dropped the trolling motor and turned on the graph, no power to graph. come home pulled graph off and checked. graph works fine. checked wiring to graph and found no power. i cant find a fuse block nor can i locate where the wiring for the graph ties into its power supply. can someone help me out, i have search under the dash and replaced all wire connections with solder connections and heat shrink. still no power to graph.thanks guysallan
