Strobes does not fire (I'm in panic mode. Trip is tomorrow)

Hey guys, I'm gonna cut this short and just explain what's wrong.

I'm using a Sony Nex 7 + Nauticam housing

My friend loan me 2 nikon SB N10 strobes for my manado trip which is tomorrow morning

I have used strobes before, mostly borrowed from friends because I am still saving up for it but the strobes always worked for me.

So I'm testing out the strobes and no matter what I do, the strobes don't fire. Earlier when I picked up the strobes my friend demonstrated to me & the strobes were working.

I am desperate for help.

My camera does not offer much settings for flash or strobes.

The only thing I have on menu is flash > flash fill / slow sync / auto flash / rear flash. All which I tried and still failed.

I tried all The strobe settings as well ttl/ttl, manual /full and all the In between.

Batteries are fresh and new.

Thanks so much in advance.

Just to get a bit more info so we might be able to help you.....

a. How are you connecting the strobes to the camera? Via using fibre optic?

b. You've got the pop-up flash active on the camera, right? Is that working ok?

c. When you fire the camera can you: see the camera flash?

d. Can you see the light through the Nauticam housing fibre optic bulkheads?

e. Can you see the light through the fibre optic cables if you detach them from the strobes and look down them?

Fibre optic

b. You've got the pop-up flash active on the camera, right? Is that working ok?

Yes it fires. I can see it. It works well

c. When you fire the camera can you: see the camera flash?

Yes I can

d. Can you see the light through the Nauticam housing fibre optic bulkheads?

Yes it works. It flashes

e. Can you see the light through the fibre optic cables if you detach them from the strobes and look down them?

Yes. It lights the little windows in the strobes

OK.....

So it looks like it's the strobes themselves that might be the problem. Maybe they aren't getting enough light through the fibre optic cables to activate them? (I'm struggling a bit here as I'm not familiar with those strobes or that housing or camera (!)

Have you used this type of strobes and fibre optic cable before with your housing/camera? Are you using the Nikonos cable? The manual says its the

Hey AK, just wanted to make sure you had the strobe manual and could work through all of that.

I appreciate you might have it already but just trying to cover the bases.....

Have you got "Underwater Flash" enabled? (page 22 of manual)?

.... and Disable Flash has not been selected (page 25)?

If you hold and place the strobe's optic plug hole in front of the camera flash, does that trigger the strobe? If so, it's an issue with the fiber optic cable.

Yes i also agree that its most likely a problem with the fiber optic cable not throwing out enough light for the strobe to fire.
