regent hydro 15 starts fine but then stops when I leave off brake /clutch

mower was fine over the summer, left it outside with a little rain one night and came out to start it and it would just die after I leave off the brake, I checked the two switches under the mower they are working I unplugged the seat switch and checked it with a meter and it seems to work, however I now can start the mower without being on the seat, never did that before that I can remember. I saw a post on the net about there are relays that could of gotten wet and caused this issue?
