I don't know anything about electronics so I appreciate all the intelligent responses.
My previous graph was also a Humminbird, so when I installed the new graph, I used the same power line that was used for the previous graph. (It had the exact same connection going into the graph) I will look and see if I'm able to rewire the new power line. It connects into a long bar of connections and switches under my boat dashboard.
Yeah, so disconnect it. Add 10 gauge wire to extend it back to your battery if needed and wire it direct. That will probably fix the issue...unless your battery is bad.
Don't forget to add a fuse as well
