problems connecting a Y cable
« on: April 04, 2010, 07:52:51 PM »

Hi everyone! I'm new to the boards and have a question about running two transducers. I have a 798 ci si that i've had since last august. I have the SI transducer mounted on my jackplate and it works great. I've read about guys running two tansducers for better high speed operation. My boat already has a humminbird transducer from a WIDE 128 mounted to shoot thru the hull. I called humminbird customer service to see if I could use this tranducer with a y cable and an AD 629 cable, which converts two pin transducers to 7 pin tranducers. I was told that this would work and that my head unit would switch tranducers automatically once I went over 10 miles per hour. So i got the cables on friday hooked them both up and took the boat out on sat to test everything and fish a little of course. haha. Well unfortunatley the new set up is not working. My SI is working but the dual beam part of the si transducer is not giving me any readings and thru hull transducer doesn't seem to be working at all when i start going fast. I am missing something here? Anyone try a similiar set up and have it work. thanks for any input or suggestions!

Varsity981,

Welcome to the forum.  First, the Y cable will eliminate the 83/200kz 2d portion of the SI transdcuer completely and does not automatically switch between the two transducers after 10mph.  If someone told you that, they are comepletely wrong!  Thats why you are not getting any readings from the 2d of the SI transducer.  The only way to use both for 2d would be to put in a transducer switch.

Then as for losing bottom at speed, how did the shoot-thru-hull transducer perform on your old unit at speed?  You could hook it up directly without the Y cable (eliminate the SI for now) and see how it performs with this setup.

I would recommend updating your transdcuer.  If I am not mistaken, the Wide128 only used 200khz, correct?  So you also do not have any 83khz with this setup as well.

I hope that helps a little!

Robert

Hi Robert,
Thanks for the feedback...I was told that by a woman when i called H-bird customer service to find what cables i would need .... :P   My 128 tranducer worked well at speeds with my old 128 head unit but doesn't do anything with the 798 with the y cable...I'm going to follow your suggestion and connect it directly to the head unit to see if it works works.  I'm not sure if its 200...I'm pretty sure it is a single beam.  On the bass boat central forum i saw some posts about someone having a similar issue with there set up and issues with there interlink...they fixed the problem by wireing directly to the batter instead of into a fuse block.  Do you think this would have any impact?  thanks again for the help...this is a great forum...i'm learning alot by reading everyones great posts!

I dont think that wiring directly to the battery will help, but if you do make sure to  put a 3 amp fuse on the positive lead at the battery.  chuck
