Thread: 798 SI help please

it does it even when engine is off and other unit is off

Gene, did you ever find the answer to this problem? I have the same issue. Thanks.

KJACK,YES FOUND PROBLEM,WHEN I HOOK UP DUCER THE EXTRA CABLE I JUST ROLL UP AND THAT WAS WHAT CAUSE IT,WAS SUPPOSE TO FOLD IN MIDDLE AND ROLL,THAT WAY CABLE IS WINDING UP BOTH WAYS.HOW I FOUND OUT WAS BOUGHT A 998 AND AFTER A WHILE IT DONE IT ALSO, DON G WAS WITH ME AND WE DEFAULT THE UNITS AND REWIRED THEM AND THEY HAVE NOT DONE IT SINCE,OVER A YEAR AGO. I WOULD SEND IT OFF AND THEY WOULD +FIRST DEFAULT IT AND THEN SAY NOTHING WAS WRONG, BUT IN A FEW WEEKS IT WOULD DO IT AGAIN,PROBLEM IS NOW SOLVE. MAKE SURE U DEFAULT IT FIRST, HOPE THIS HELP

Thank you, Gene. This is great information. I have my extra TD wire rolled neatly all in the same direction. I have tried everything but never thought of that. I will try it. Thank you, Merry Christmas! Keith

My 798 does the same thing also. I too will try this trick. Let me see if i understand you correctly. The excess transducer cable should be folder both ways (once towards the transom and then the next wrap back towards the bow) until you use all of the slack cable, to eliminate external magnetic interference into the cable?

Coil the excess cable into an 8" coil ...

Then, twist the entire coil into a "figure 8" and fold 1/2 of the figure 8 (4" coil) onto the other 1/2 of the figure 8 ...creating a duo-directional 4" coil ...

I never knew that! Going to try it, I have a 1198 doing that.

Lord have mercy, just when you think you have heard it all something like this pops up. I just installed SI on my boat but have not had a chance to run it yet. It is a Lowrance HDS 7 touch screen. Wish my transducer was as compact as yours. Mine is about a foot long. I will check my cable tomorrow.
