I bought a boat that had a Humminbird 561 Sonar dual beam fish finder in it. We have checked out all the connections and has a new battery in the boat and cant even get it to turn on. Is there something like a fuse or is it possible that it might be too old it looks brand new but I think it is 10 years old. I tried to contact Humminbird trouble shooting but was put on terminal hold left my phone number and never got a call back. Any ideas what to do ? Is it worth fixing or should I just move on ?
