What happens to a non-sealed speedlite when getting wet?

Electronics don't like to be on and be wet, that's a pretty simple rule.  However, once my 430exii tipped over into a huge thing of water, then it fired when it got wet.  I was terrified and yanked it out and took out the batteries immediately and it ended up still working.  So, that's about as wet as it can get and it still worked.

Thanks, this is the information I was looking for! It proves that there's no part in it that instantly breaks when coming in contact with water, so potential problems seem to boil down to the usual corroded pcb issue.

Every time I use my flashes in dusty or wet conditions I just put them into a plastic bag close the bag whit  some duct tape and then they are waterproof too nearly everything.  I never had any problems to remotely trigger them trough the bag. I have used every combination of 7d, 430ex I/II and 580exII. Just be aware that the bag does not direct touch the Flashhead because it will melt at hi output values.

I have spilled beer on my 430exII several times.. (party photography) Some buttons aren't working anymore. But it still flashes.
A Canon tech guy told me that the broken flash could transmit too much power to the camera via the hotshoe and that I should stop using it.
I don't use it anymore and have upgraded to 580's..

Mt Spokane Photography:
There is a large and very high voltage capacitor in the flash that can push voltage at a high current enough to pop almost any of the internal circuits, so anything is possible if it gets wet.  However, I have not heard of serious damage happening.
 
It  is virtually impossible to get a good photo using flash in the rain, the light reflects from every drop so you have your image full of ugly streaks and reflections.  Its just a matter of covering the flash with a plastic bag to keep it from getting wet, you can keep one in your pocket and slip it on if it starts to rain.
