My fishfinder 565, just suddenly stoped working. We were in the boat and all of a sudden it went dark. Can there be a fuse of somekind that could be replaced?

I would suggest getting a transducer extension cable and installing the t'ducer on the left side of the boat.

I would imagine it might have something to do with water turbulance? Do you have a sensor thats located at the bottom of the boat somewhere? In my grandpas boat, the sensor is at the rear bottom near the hole where you can drain the water, if your going very fast it doesnt work very well, slow or stopped and it works fine. If you have that type of sensor make sure whatever holds it is tight so the sensor cant move around.

either that or you got some funky wiring issue lol

Their may be a loose wire that you missed somewhere. You'd probobly want to take it to a repair shop.

Check the transducer for cracks or large amounts of growth. Also make sure the transducer is still in the correct position as when installed. Next check the entire length of the cable to make sure there are no breaks, kinks, or stress points.
If you have to send it back for service MAKE SURE YOU BACK UP ALL OF YOUR DATA AS IT CAN BE RETURNED BLANK!

If you need further help, I’m available over the phone at https://www.6ya.com/expert/saam_2816e29ba1070532

you can get a specialist to come and fix/reapply the sensor to the boat and possibly fix it if it is broken var fctb_tool=null; function FCTB_Init_4fdf0f4e4d1b403489dd188ff9311fa0(t) { fctb_tool=t; start(fctb_tool); } FCTB_Init_4fdf0f4e4d1b403489dd188ff9311fa0(document['FCTB_Init_3475a15565eb478ea69972d3c6d88377']); delete document['FCTB_Init_3475a15565eb478ea69972d3c6d88377'] var fctb_tool=null; function FCTB_Init_a70c5362962d40be976e65b2158646e3(t) { fctb_tool=t; start(fctb_tool); } FCTB_Init_a70c5362962d40be976e65b2158646e3(document['FCTB_Init_379c2b6472d1424f847e6d43703fa3ad']); delete document['FCTB_Init_379c2b6472d1424f847e6d43703fa3ad']

More than likely you have your sensor run underneath the boat and therefore the sensor is directly in the water. When you speed around the hot water on top is what your sensor is picking up, when you slow, you are allowing the sensor to pick up on the colder water just inches below the surface

Check your fuses first, the check your connections at the horn button and at the horn its self. All else fails take two pieces of wire hook one to the pos. and one to the neg. on your battery and test the horn that way to see if that is the horn went out.

Not sure where the realy is, but there should be a 30 amp fuse in your fuse box. Did you check that?

Hi!
Installation of the speed/temp wheel is quite easy, here's a manual:
SW Speed & Temp
The new sensor cable plugs into the square plugin in back of your Humminbird....it's the small square connector with 4 holes.
Best of luck!
Mike

according to the manual... 10-20 VDC

Please rate this solution.. thanks
