[DG11] Speed no run with D800/P17 and itc-5
I have a I70s, with d800/p17 transducer and itc-5. Has one year, and never went ok but last month, sometimes run and other 0,0. The transducer it´s clean and free, last times when i sail at 5 knots, i can see 0,1 or 0,3 in the velocity, over time i can see to 3 or 4 knots, and last times was in 0,0

Hi Atica,

Thank you for your enquiry.

We would first recommend testing the speed transducer, please [http://forum.raymarine.com/showthread.php?tid=1438] see here for test details [/url], if the transducer is faulty, then please replace it.

If the transducer tests correctly, all the connections are secure in the itc-5, then check the LED in the itc-5 next to the speed connections, it should be constantly lit.

If it is flashing or unlit, then the itc-5 is faulty and will need to be replaced
Thanks
Derek

Hi Atica
Thanks for the feedback,

The results suggest the Transducer is communicating fine, if you remove the transducer from the hull fitting and spin it, does the speed react immediately and show a more realistic response?
If yes, then the issue is more to do with the hull fitting, maybe the transducer insert is not seating down properly and so is not in a good flow of water or there is some disturbance effecting the water flow across the paddlewheel? Possibly even a fault with the transducer where it is not reacting to the spinning paddlewheel?

It sounds more like the issue is with the Hull transducer than it is with the itc-5.

Regards
Derek

Hello DereK,

the speed it´s alwais 0.0 two weeks ago, when it´s in water and out of water, i do the testing of speed transducer out of water, everithing it´s ok, i connect the green cable and move the spin and the speed it´s 0.0.

Hi Atica,

It really sounds like the transducer is faulty, I suggest to get a local agent to test the transducer and replace it.

Hello Derek,

thank you for your patience.

I put the transducer on water I go to see diving, was perfect on the hull, i move it with my hand but read 0.0, and my surprise was that when the transducer it´s on water the light green of itc-5 is intermitent in the speed. The depth it´s runing well and the light it´s alwais green.

The i70 read 0.0, the boat are moving and the light of itc-5 it´s intermitent. When transducer are on water and the depth it´s runnig.

where do you think it´s the problem?, transducer or itc-5.

Thank you

Regards

Alejandro

HI Atica,

Based on your feedback, I believe the fault is the transducer and it should be replaced.
