Hello all, I am seeking a blueprint or some sort of diagram for the Raymarine L770. I purchased one at an estate sale and have no power cable for testing it. I just needed to find a schematic to determine which pins are positive and negative so I can try hooking it to a battery. Can anyone point me in the right direction?
Thank you in advance.
