Battery died due to headlights coming on while car was parked. Lights can not be shut off from switch, opening the hood I detected electrical smell. I removed the fuse box cover and noticed water collecting and stains. I pulled several fuses and found three that melted. All this happened after a ice storm followed by a warming up and melting trend the water collected on the fender brace and leaked into under hood fuse block. I replaced the fuse block and all is ok. Though fuses were melted apart they still made contact and easily could have started a fire. I drilled holes into fender braces and redirected the water.
