Not positive, but I THINK I have the same sounder on my boat- is it a color CRT screen?
Mine can be fickle at times, especially the grounding.
Make sure it's grounded directly to the battery or a negative buss.

Well, the SI NG is the serial interface. You need to have the serial cable installed and connected to the serial port of another piece of equipment, i.e. GPS, or you will get a SI "No Good" when you run the test.

Need to give more of an explanation of "looses bottom". It could be something as simple as a range or gain adjustment or you need a new transducer. Just because the transducer ticks, doesn?t mean they work.

Here is the manual for that unit. http://www.furuno.co.jp/en/product/marine/document/fcv667_ome.pdf
