Why are shots overexposed in TTL Mode

[W8less]

Sea & Sea YS110 - sync cord - H/W bulkhead Converter - Olympus SP350.

What am I doing wrong. With the strobe set in the TTL Mode, all of my land test shots are completely overexposed. The strobe works fine in Manual Mode.

All connections appear to be OK, hot shoe board seems to be seated correctly.

Hi W8less-
It would not be the strobe if manual is working and light emittance is fine. It may be the camera to H/W converter. Please check with your authorized dealer who sold the system.
