Hey everyone,

Just back from a dive this evening and had an issue with one of my YS-D3 MKIIs. It seems to only be firing at full power, setting the dial isn't changing the strobe output. Strobe is set in manual mode.

Strobe is about a year old, maybe 70ish dives so far.

Any ideas?

As I recall this is a failure reported in any type of strobe, the circuit that cuts the strobe output has failed but the trigger circuit still works. There was a reset procedure for earlier versions of S&S strobes, but don't recall seeing one for this model.

As a workaround try it in TTL to see if it works adjusting power. You could run it in TTL triggering off the duration of your other strobe?

In the meantime I would be calling your dealer about warranty - do this first if it has not expired as yet.
