FI light help

[PROJECTpatience]

I have been looking around on the forums and I cant seem to find an answer to my problem so hopefully someone can answer it for me. I have a 04 Ninja 636 and my FI light keeps lighting up. There is no pattern to how it is going on or off, its just intermittent. Sometimes it will stay on for only a couple seconds and sometimes it will be on for twenty seconds or so. The bike runs no different with the light on or off. I did get stuck in a pretty good downpour two days ago and I read on here that the water could of gotten in somewhere and could be causing my light to turn on but I figured it would of evaporated by now. So basically I am looking for any suggestions on what it could be and also advice on if I can keep riding it how it is or should I stay off of it. Thanks.
