So on my dive today my S&S YS-01 wasn't working. It worked intermittently on my previous dive earlier this week. As soon as I'd get in the water, it would act like the batteries had died, even with freshly charged batteries. I was able to replicate the issues on land by pressing on the battery door. If it's uncompressed, the strobe will charge up and give me a ready light. As soon as I press on the door again, it loses all power. I haven't opened it up after this dive as I'm still letting it dry, but when I looked in the battery compartment this morning when replacing batteries, nothing looked amiss. I just returned from a liveaboard a few weeks ago with no issues.
Anyone else had this issue? What should I check to see what the problem is?
