My strobes have been acting flaky lately where one strobe is not firing intermittently. I've looked at a number of possibilities - strobe batteries, flash trigger batteries, fiber optic cables - but nothing has resolved the issue. This evening I noticed there was a loose or severed wire connecting the flash trigger to the hot shoe plug.

Has anyone else experienced this problem before? The flash trigger is only about 2 years old - I'm surprised it would wear out so quickly. Although I did have a one where one the wires for the LED lights broke. I don't know if I'm "man handling" these flash triggers or if they are really fragile. Can I get this repaired thru Nauticam or a certified Nauticam repair company (i.e. Backscatter).

I have seen a very similar failure on a buddies Nauticam flash trigger Hot Shoe. In that case the loose wire was inside the hotshoe part, but very similar. This is also why I travel with a USB-C powered soldering iron! I've now fixed a few housings with wiring issues of several kinds during trips.

This is a very simple repair that you can do yourself if you are even a little bit proficient with a soldering iron. If not you, perhaps a friend with some experience? Just unscrew that hot shoe plug to gain access to the connection points and resolder the loose wire.

These fine wires will be quite fragile. It looks like a bare copper wire - no insulation so I'm guessing it attaches to the ground of the hotshoe - the metal around the outside - the silver piece attached with 3 screws. You could take off the screws for the hotshoe and have a look - as Dave says you might be able to re-solder it - or if it was attached to the and you aren't skilled in soldering it might be possible to clamp it under the metal part of the hotshoe assuming this is where it came from.

I very much doubt Nauticam would repair, they would want to sell you a new one. Looks like yours in a manual trigger board where the connection is soldered. An alternative would be to but a new bulkhead cable and solder it on as there's only two cables needed - see this pic of the other side of the board. If you could source a 2 cable manual hotshoe cable you could remove this one and solder it on. If you don't have the gear or soldering skills any competent electronics repair store could solder it on. Bu probably simpler to solder the cable up at the top end.
