76 Plymouth Valiant won't start

Wow, I got one notice of a reply; that's a great welcome.

Bad Sport - No, this is her daily driver. And the first thing I noticed, when I popped the hood, was corroded battery cable connections. She isn't getting my messages of preventative maintenance so this is the usual; when the car doesn't start, she says something...
And it is definitely a "fusible link", as it has a tag, in several places, on the wire that says so.

67Dart273 - It is an auto. The last thing I did to it was take loose, clean and re-secure every connection I could find, including the bulkhead connectors.

Rapid Robert - I can't tell where the wire that got hot and melted some insulation off is grounded. It looks like the wire runs from the battery but it goes in and out of the wiring harness and changes from red to black and back to red and to black again! But it does have a tag with "fusible link" on it in several places, one is right near a bare spot.

I have some pics of the wires but it was too dark when I took them. I will take some more tomorrow afternoon, maybe with an actual camera, instead of a cell phone and post them.

Thanks for the quick replies guys.
Talk to you all tomorrow afternoon or should I say later, as I just noticed it is past midnight here...
