I killed one D-370 on the bench that went with just a whimper and it was gone, but this one was in the field and had been for about three weeks when it went up in smoke. I've never seen one fail so dramtically. The slave flash is still working, the PIR tries to work but is not well. Any ideas what could cause one to fail so severly? The case is fine, it was not in a forest fire, there was about a tablespoon of water in the bottom of the case when it was opened up.
