OK, It sounds like there is a short in the start circuit, which is taking out the Instrument fuse... Check at the start button, then the starter relay (Which is located at the fuse block), it's an "ice cube" small plug in device which controls current to the starter solenoid. The starter relay may have gotten water in it. See if you can remove it & blow it out. If water does come out consider replacing it. It's not too expensive around $12. Also dielectric grease can be purchased at your favorite auto parts store. Good luck.
