went to start my F450 7.3 and when I turned the key on it went crazy, wipers started going, gauge lights flashing, radio came on and off, turn singles the same, you can hear every relay in it clicking like crazy, even the ones under the hood, it won't turn over just clicks, have had the radio come on by itself once in a while but NOTHING like this. Nothing works except the right turn signel, when you turn the left on on the emergency flashers come on. in another forum I was told it was the GEM module but I pulled the fuse box and checked it. It seems to be fine, no corrosion what else could it be
