climbrox 0 Posted October 10, 2005 Well it finally happened. I've only been shooting underwater for a couple of years and had so far managed not to flood anything. This weekend I somehow flooded one of the bulkhead connectors on my Light& Motion TitanD100. Strangely enough the sync cable still works even though the connector is fried. Using the same dual sync cable I just switched to the other bulkhead for the next dive but now I'd like to get the problem fixed. Is this easy to do or do I need to take the entire housing to Backscatter for servicing? Share this post Link to post Share on other sites
davephdv 0 Posted October 11, 2005 Get it fixed. If there is salt water in there you eventually have a problem. If salt water got in your synch cord it can migrate up you cord and potentially fry your camera or strobe at the worst possible time. Share this post Link to post Share on other sites
UWPhotoTech 0 Posted October 11, 2005 It's a very simple procedure to replace the sync bulkhead. Unplug the sync wiring from the board in the housing and using a 19mm wrench unscrew the old bulkhead. Reverse the procedure to install the new sync bulkhead. Having Backscatter, Light & Motion or us B) do this for you will offer the advantage of having the housing pressure tested and function tested to make sure that everything is in good working order.

ikelite 0 Posted October 11, 2005 Read precautions from: http://www.ikelite.com/faq/faq_syncwiring.html Caution: The Nikonos connector must be aligned correctly, and should be STRAIGHT when it is inserted into the camera. It is possible to start the connector at an angle, tipping it up to straight as it goes into the camera; but this procedure is much more likely to extrude or pinch the "O" ring, causing a leak. The Nikonos system should be very dependable with reasonable care in alignment and installation of a clean connector that has been lightly lubricated. Housing Caution: Care must be exercised when removing the sync cord especially from housings that have a Nikonos socket installed on the top. Removal should be done with the housing inverted to prevent any water drops from entering the bulkhead. The two small spring loaded contact pins in the bulkhead are especially susceptible to sticking and corrosion from moisture. These apply to Nikonos sync cord from anyone including Nikon............

climbrox 0 Posted October 11, 2005 Thank you very much for the helpful advice. I suspect a pinched o-ring as ike described is what caused the problem. Something to look out for next time. I think I'll buy a 19mm wrench and take a look although a general service and testing at BackScatter is probably overdue. Share this post Link to post Share on other sites
james 0 Posted October 11, 2005 Thanks Ike, that is very good information. I flooded a bulkhead in Bali and unfortunately, it's the Nikonos style. Those two spring loaded pins stuck in the down position, but otherwise I was able to clean it up and keep it working. Thank GOODNESS those two spring loaded pins aren't used for manual flash firing, or I would have been out of luck. As it was, I was able to continue using the setup because the trigger and ground pins were still making good contact. Cheers James This all reminds me, I need to get this sucker serviced!
