So I've got a fish finder with a big 5" or so screen and a small depth finder that looks kind of like an old school pager. Both are humminbird. I see two black blocks off the transom on each side of the boat that say "humminbirg", so I assume they are the sensors. Problem is, neither of the finders power up. How to I begin troubleshooting this? I have replaced all the fuses in the dash by the ignition. There are 7. The manual says there are 8, but the 8th spot is a cigarette lighter. I can put pictures up later when I get home if that will help. Thanks.
