    This always happens after rain, the only way to turn the truck off is by removing the instrument cluster fuse, if I put the fuse back the ignition comes back on, even if I took the key out.

    Can someone tell me what should I look for, cracked wires or bad chassis-ground connections, bad jacks ? If it's ground, how do i know which one is ground since they're all yellow and there's hundreds of wires.

    Thank you.

    Look behind the drivers seat for a panel that pops off with a fuse box inside and has got water in it pull all the relays out and look for green on plug in on relays you can use a large zip look bag to put fuse panel in after you clean all plug ins and have it turning off like it did before?If your on the road you can buy a batt. cut/off switch like race cars use when you park it for the night.

    X2 on this advice. Had a Century that would do it's P.O.S.T.(power on, self test) like I turned on the key when I was parked during moderate rain storm. Thought my truck was possessed until I called my company's breakdown. They told me to do the same thing, and sure enough, when I opened the cubby door, it was raining inside the compartment almost as much as it was outside. Wrapped the connections with plasic Saran wrap and the problems gradually stopped. It stayed that way until I got to a shop where they could reseal the truck. Not sure what seam was leaking, they just shot silicone in every crack and crevice they could. Never had another ghostly episode after that.
