Something shorted out when I went to start my truck..... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

....and now I need some help to figure this out. I went to start it and it sounded like the battery was low and it wasn't wanting to fully crank over. Then I noticed some smoke under the hood and when I poped it I saw that a small 14 gauge or so wire that ran from the negative battery post to the core support had burnt up. From that same spot on the core support is another small wire that connects to the frame and it didn't burn at all. My negative cable is attached to the alternator bracket with a normal large cable (6 gauge or so) and there is another larger (again I think 6 gauge) wire that goes from the block to the frame in another spot. My question is why do I need these extra smaller wires that go to the body? And more important why did just that one burn? I am assuming there is a short in the starter but never ran into this so I could use some help or advice to trouble shoot this.

BTW its on an 85 C/10 with a 350 if that matters at all.
