I had a similar problem recently on a Friday I was driving around doing some deliveries (about 5 stops) during a heavy rain with no problems. After the last stop when I turned it over just a click no cranking. When I looked behind the cover where the OVP is (to see if KSE fuel injection had melted) there was water dripping on it. It was getting behind the gutter because the trim above it had come loose and the rubber seal above had slid down behind it. Pretty easy to fix, just pull it all out and insert the rubber seal down from the top. After a lot of drying and a jump-start (the battery checked out good though?) I got her rolling again. Similarly it has not rained much since.
I seems that if it were something protected by the OVP it would blow the fuse. Unless you've gotten a real bad streak of luck (OVP manufacturing defects) the only thing I can think of is to really clean out those sockets (that the OVP is inserted into) with a tiny wire brush, a vacuum, and some electrical cleaner in case there was corrosion.
I wonder how many fuses go through OVP's rather than the other way around as it should be. Mercedes should be ashamed that they haven’t solved this problem.
