Humminbird 565 Fish Finder Problems???

[PSourasinth]

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.

Ooops... perhaps that is why it is not working now?

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.
