I was driving home from work today. Half way home, my engine hesitated and then cut out on me. I lost all electrical power. I smelled smoke (electrical) and then got smoke coming into the cab. I pulled over immediately (ironically it was a fire station). Smoke was poring out from under the hood. I popped the hood and found the smoke was coming from the negative terminal on the battery. The chassis ground cable was fried and had burned through its plastic. I tried to pull the cable off, but burned my fingers. The connecter burned through and it disconnected itself from the battery. Gravity pulled it down and I watched it melt a 2" hole down the side of my battery. So, my wife pulled my home and I'm inspecting it now. The one thing I found that was interesting was that my ground cable that goes to my engine block was no longer connected. No bolt no nothing. It's just dandling there. I had a thought just to hook it up and see if that was the problem (perhaps a loose bolt that finally gave way and is lost on the road), but I figured I'd better post here first to see if any of you have any suggestions. I don't want to hook that ground up if there's a big possibility that there is a short somewhere that could cause a fire and make the damage worse. I examined under the instrument cluster, steering column, radio, dash, etc and could not see any signs of a shorted wire. I checked there first because I noticed smoke first in the cab. I could have come from the engine compartment, though. What do you think? Should I be suspicious about another short somewhere in the system? Would the main ground cable coming off the block be enough to fry the other ground?
