2nd Dead Regulator In 2 Days

Hi, I have a Tiger 955i (2003) and have a recurrent problem with my regulator.
Last week I went to Germany but after driving in the rain I couldn't start up my bike anymore. The battery was dead, so I putted a new battery, started up the engine again, but I saw that the warninglight of the engine on my dash didn't went out. So I stopped again and measured the regulator output-voltage which was only 0.5Vdc. The alternator was OK. I replaced the regulator and it was OK again. The day after we drove again through heavy rainfull and again the regulator went dead. The battery discharges then slowly while driving and I can't start the engine again. So I was forced to leave my bike in Germany.
FYI, 3 years ago when I bought this bike I've also replaced immediatly the alternator and regulator (R99 MOSFET-type) because my predecessor had the same problem without knowing it.
So I fear that it's due to the rain that the regulator fails. Waterintrusion somewhere?
Does anyone has an idea what can be the cause?

 

That's what I'm intended to do but I wanted to gain some time to check if maybe someone knew that this is a 'typical' well-known bug or design-failure for the 955i-series.
Or someone who had the same experience?
You never know.

 

Hey, I don't know that there's was a recall for this year and type. I know there was a regulator-recall for the Street triple 2009.
Anyway, I've changed already several regulator, and the last was a MOSFET-type (Eltrexworld R99). But the problem is that it went dead after heavy rain. So I assume the problem is that water causes my regulators to break down. And that's strange and can be anywhere. Any idea?
