D70 iTTL housing problems with DS-125

The excellent Ikelite have upgraded my veteran D70 housing with the new iTTL conversion circuit - just in time for me to fly out to Bali next week.... but I have two problems:

1. Sometimes the camera will not take a photo when the shutter is depressed if the strobe is turned on. Once in this state, switching the camera off and on fixes the problem

2. When the controller is in TTL mode, the flash is not syncing with the camera. It fires, but does not light the photo at all

Has anyone else had such problems? I guess I am doing something wrong, but I'm not sure what...

The strobe is set to TTL, connected with a 4103.51 cable with the blue band at one end, and the conversion circuit is set to DS-125 (although it behaves the same when set to DS-50)

I'd love to sort this out before flying halfway around the world!

Is your strobe at the proper EC evel?

"DS-125 SubStrobes with Serial Number below 2,500 require a $150 update to operate with the latest TTL conversion circuitry. DS-125 SubStrobes with Serial Number between 2,500 and 4.999 operate well with the latest TTL conversion circuitry, but require a $50 update to provide optimum performance. "

Yes, it is Peter (I think!) - I've tried it with two strobes, both with serial numbers greater than 5000 with the MOD-NC sticker

Ikelite have asked me to return the converted housing so they can take a look. They've never had this problem before... guess I'm just a bit unlucky

Thanks anyway (and thanks for your website - a goldmine of D70 underwater information!)

Check to be sure the connector is completely in the camera hot shoe and stays there when closing the housing. We will stop everything to exchange or repair whatever is necessary to get the equipment operating for your trip to Bali.............

Now that's customer service!

I'm having the same problem with my D-70 and DS-50's. For a while, only one strobe would fire while the shutter was open, and now neither are firing at the right time. It is almost like a pre-flash because I can see the flash in the view finder. In manual mode, everything works fine.

The problem was caused by a defective cord. Ikelite found the cord had water damage at one end.

Replacement in hand, I'm on the way to Bali now. Thanks for your help, and thanks to ikelite for being so quick at finding the problem
