Hi,

I am reporting my problem with S&S i-TTL converter. While, I am using it
with my Nexus D-200 housing + 2 x Z-220 (later w/ 2xYS120Duo), battery
compartment of TTL converter start disintegrated in underwater. It looks like it has
something to do with electricity. Battery compartment was not fluded & converter
is still working but, it is basically melting.

This problem wast reported to S&S through the dealer.

This unit is obviously not ready for prime time. The problems continue. Besides mine not syncing the 2 strobes & problem with smooth rotation of adjustment knob, the jam nut on the connector (to housing) froze in place. The stainless material used for the connector is not totally compatible with some bulkhead materials - electrolysis problem. S&S should have used the same material as their sync cords. At least my Nexus bulkheads are happy with that. Still waiting for repair or replacement from the S&S Service Center. It may be on Ebay soon <_<

Could you post a picture or two maybe? Is it the plastic around the battery compartment that's melting due to heat or what?

Sounds disturbing.

I sent pictures to Sea&sea & they will review it first & make sure I did nothing wrong first.

If you are using S&S i-TTL converter with NEXUS (which has metal camera base. Sea&sea housings are using plastic base) HOUSING + INON Z220/Z240 strobe, just BE AWARE of this problem & would like to suggest to wait for further information/instruction.

Re jcclink's comment,

I also, noticed S&S recently changed material of Sync connector from Aluminum to Stainless steel and jam nut is still aluminum & experianced same problem (nothing to do with converter but, regular cable I am talking about). It is rapid corrosion problem & happens when two different metals meet each other. At this present time, all you can do is put more grease to thread.... & hope they find a solution.

Regarding the converter, both the connector & jam nut appeared to be stainless. The Nexus bulkheads look like anodized aluminum. Can someone confirm this? (All my stuff is in the shop at the moment so can't check.)

[shchae]

Here is picture of my i-ttl converter. It is not just coating is off but, you
can see rough surface of battery compartment. It is looks better
as completely dry now but, was looked ugly when it was wet & it was
melting like green gel( Can someone tell what it is ?? Is it O.K. to touch ???).
It all happened in total of 5 dives in 2 days.

S&S believes it happens because Nexus housing is using metal camera
base(grounded with camera ?) & it also, happen with Inon Z-220/240 strobes
ONLY.

I shipped all my stuffs to them for further investigation.

Interesting... so far I my TTL converter hasn't had a meltdown yet... but I guess I'm safe with my S&S housing.

Sorry to hear about the your problems Sam.

I too, am very sorry to hear about your problems.

I have the Sea&Sea TTL converter with the NEXUS D200 housing, an INON Z-220 and Z-240 strobe. I've logged about 20 dives with the set-up so far, and have not experienced any problems remotely similar to the photo you have posted. The interior of my unit's compartment is spotless as well.

Just curious, did you ever change the battery on the unit?

I'd be interested to hear what Sea&Sea analysis turns up.

Good luck.

Michael.

I had 25 dives on mine in Bonaire (D220 - Subal - Inon Z240 (2)). I just changed the battery last night and it all looks like the day I got it.

Strange yours acted this way. Keep us informed.

O.K. thanks for good words....Few more things....

1.S&S is/was aware of this problem when I reported & it was NOT just me having problem but,
somebody already had same problem.

2.I did not want to make it too big issue out of it but, my Nexus housing was damaged too.....
Those of you who did not had problem, please, carefully watch your HOUSING & converter.
My housing was almost new & it looks like 10 year old housing now with corrosion everywhere.
I shipped my housing to S&S too.

3.My converter was new + new battery & it was first diving trip since I got it. It was i-TTL
converter II designed for D70,D200 & D80 additionally & only few of them were sold so far.

I had the same problem. I'm not sure what version of the converter I have. Mine was used with a D2x housing. I expect that strobe type is irrelevant because the electrolysis occurs between the converter and the housing. The problem is the Nexus housing which should have had an insulated base.

My housing made it through the ordeal without any damage and I had 10 dives or so without any ill effects until the dive things started to happen. I noticed that the light on the converter turned red in periods. (I thought the battery was dying, but it performed great for the entire dive.)

A plastic base for the Nexus, a insulated battery compartment would solve the problem. I hope both Sea&sea and Nexus fix this as the combination is very popular and many will be unhappy if no solution is presented.

O.K. It is now confirmed that it happened to other member too. Now I will share
picture of my poor housing.

The electrolysis is the result of connecting the stainless converter connector to the aluminum bulkhead on the Nexus. S&S should go back to aluminum connectors (like their sync cords are/were). Something that will defintely help is to attach a small zinc washer to the housing. The zinc will dissolve instead of housing parts. I've had my YS90's connected to my Nexus D70 for a couple of weeks via S&S cords with aluminum connector with minimal problems. Only some discoloration of a few anodized parts. This may not be the best practice but I figure if it doesn't leak don't mess with it. So far so good. I don't view this as being a Nexus problem. I'd hate to see a plastic camera mount. It would be more flexible than the metal one & probably cause some control alignment issues, especially with the heavier lenses like 17-55 & 105VR. I would not recommend using this converter on a Nexus housing (no experience with other makes) at this time until S&S fixes the problems. Not holding my breath for a factory replacement unit either. Mine may or may not make a good paperweight. In either case I won't dive the current design again.

P.S. It possible that the metal D200/D2X body vs the plastic D70 body could be playing at part in these problems.

If anyone is giving up on the S&S i-ttl converter, decides to make a paperweight out of it, or just wants to sell one. Drop me a line, as I will soon be adding one to my new S&S, D-200 set-up. thanks!

Brant - I should know in a week or 2. There's a possibility that I may get a factory replacement instead of the shop repairing mind. Hopefully the converter materials are more compatible with your S&S D200 than my Nexus D70. Keep in touch.

[BrantD]

Jim,
I'll hold off buying a new one for a while, so let me know when you decide.
I agree, I think they are fine with a S&S housing. It was one of the decideing factors for the housing. Wish now they would come out with a better view finder!

Hi jcclink and other participants of this thread!

I'm very sorry to hear about the problems with corrosion, etc. on housings with this converter that seemed to be a perfect solution to the TTL-problems in the first place!

Adding a piece of zinc to the nexus-housing (or other housing made of aluminium for that matter) also means a penetration of the original painting/coatning to get the zinc connected to the housing. I think I would be very carefull about doing this.... also because you will have to mount the piece of zinc with a screw, which needs a drilled hole in the HOUSING!!!

Even I'm not a fan of plastic anyway, I think mounting connectors/plugs on the S&S-converter like those of Delrin, found on the Ikelite strobecabels could be a possible solution to the problem.... if it's possible at all to change the connectors/plugs?
I have been using Ikelite-cables with these connectors for years without any problems.

Just my 2cents words......

Best regards from Kim Meineche

Kim,
Thanks for your interest & suggestion.
Seacam put a zinc plate in between housing & it's handle and does not requires to drill the hole on housing and we can do similar with other housing too, if necessary. Zinc will help/protect housing from Normal corrosion (On the ship/boat, zinc plate works because it is a lot softer than steel & it melt over the time. I am not 100% sure how it works with marine-grade aluminum though)& I do not think it is going to protect the housing from the problem I had as it happen all in total of 5 dive/2-3 hours.
