Humminbird 565 Fish Finder Problems???


Recommended Posts

I purchased a Humminbird 565 Fish Finder in late August of last year and am now having problems. Last year the fish finder worked flawless, but for some unknown reason I am having problems with it this year and have not gotten it to work yet this year and am asking for your help to dissect the problem.

But anyway the problem that I'm having is when I hook the wires back up to the battery and try to power the unit up, it does not power up/turn on. I disconnected the unit, then stored it inside during the winter, so that shouldn't be a factor. My batteries are all new and am wondering if I'm missing a step or am I doing something wrong and that's why the unit is not powering up, or is the unit just flat out broke? Any advise or comments will be greatly appreciated.

Thanks again.

Is there a fuse in the cable going to the battery? If so try changing them it might be a fuse.

Thanks for the reply, but there is no fuse in the cable going to the battery. The unit got wired directly to the battery with no fuse.

ouch....you probably blew the unit. You need to buy an inline fuse. Depth finders don't come with one, but you need it.

Thanks for all the input. Last night I was able to dissect the problem. The power wire that connects from the battery to the back of the unit was bad. The wire was not providing any power to the unit, and that's why the unit was not powering up. But for future references, I will install a fuse between the battery and unit, so I don't blow the unit. Again, thanks for all the input.

      On the South Shore...  The focus for most this past week has been the ongoing deer hunting season and/or watching the forecast and feeling optimistic about the cold temps over the next couple of weeks.     The forecast shows temps staying below freezing and hitting the single digits many days.  Depending upon the wind, this should make some ice and get things started,   The limited number of anglers still fishing are taking advantage of fairly mild weather for November, but that is changing quickly.  Good numbers of walleyes, saugers and a lot of jumbo perch are staged across the south shore which bodes well for ice fishing.   No surprise this time of year, vertical jigging with frozen emerald shiners is catching most of the walleyes, saugers and jumbo perch.     Resorts and outfitters are busy, continually getting ready for the ice fishing season.  Fish house maintenance, light ice rigs, bombardiers, track rigs, augers, fish houses, sleeper houses, permitting, deep cleaning, remodeling, and the list goes on.  All good stuff that helps to make the ice fishing season more enjoyable. On the Rainy River...  Very good fishing reports for those on the river this week, and there have been a few boats.  Limits of walleyes was the norm for most. Most walleyes are being caught in 10-25 feet of water jigging with live or frozen emerald shiners.    Having good numbers of walleyes in the river is desired by those who ice fish the south shore.  It is believed some of the walleyes in the river make their way out to the lake as the ice fishing season progresses, providing additional fish to ice anglers out in front of Pine Island.  All good stuff. Up at the NW Angle...  As temps are getting colder, most are finishing up deer hunting, processing venison or getting ready for the upcoming ice fishing season.  For the few that got out, reports were excellent.  A nice mixed bag with walleyes, saugers, perch, pike and crappies being caught. Very good muskie fishing for those who braved the colder temps.  Some big fish and some good numbers are being caught amongst the islands.  Late fall is known as a good time to catch muskies and this year has held true. If you haven't made reservations for ice fishing, now is a great time.  Day houses normally get out mid December with an extended season on LOW, lasting through March.  Mother Nature always dictates.  Resorts and outfitters will be monitoring ice conditions, posting weight limits throughout the year.

      They are quite the dog. He's an absolute machine, well trained, never breaks early. They have a reputation for being stubborn and mean but that dog is just friendly and would hunt everyday all day if he could. Fortunate that he comes with on the trips we go on.

      My buddy has a Chesapeake retriever but we don't bring him with crane hunting for that reason. They have an affinity for stabbing dogs eyes out. Typically if they aren't completely dead when they hit the ground they don't run like geese. I typically hit em with my barrel and that finishes them. I've had them try and stab me or kick me with their spurs. We killed one goose hunting with my buddies dog and it was dead. He wouldn't pick it up just barked at it. Must smell way different than ducks. I guess they have mites but haven't noticed them. Never seen them on them or the meat and never see "rice breast" on them. My buddies dog is named teddy after Teddy Roosevelt. He went 231/232 ducks and geese retrieves this year.

      Kettle... remembering you shot sandhills,, my brother was saying a friend of his does alot of waterfowl hunting also. He has told people he hunts with if they get a sandhill anywhere near his dogs he'd do serious bodily harm to them.   This guy claims sandhill cranes are  flea infested creatures.    You have any ideas? It's just what he was told

      @11-87   Shop the Burris line here. https://www.burrisoptics.com/   You can mount a red dot on top of a regular scope if you want but they also off lighted reticles in some of their standard scopes.   Impressive lineup of optics that have come a long way since I last looked.  Drop Tine is their economy line.  I’m probably going to look at the mid level Signature HD.   Lifetime warranty on all models.
