I drove my challenger last week and noticed my dash gages all went to the lower end and my amp gauge was at the high end. I went straight home and noticed a smell of burnt wires. Here is the plug that I found has burnt on both ends so the wiring harness will be changed out and the ignition switch as it has melted to. Hope is all goes smooth and I have another wiring harness already to go soon as I find time to pull it all apart. Take a look at my plugs that got hot and melted.
