I installed a Lowrance 510c on my boat this spring and have noticed that when I have the graph on and turn my marine band radio on (Uniden Oceanus) I get a lot of static to where you can't hear any transmissions on it. I have the graph wired to the battery with a separate wire and the radio wired to the boat's wiring harness. Wondering if it would help to wire the radio with a separate wire also?
