Default Confusing Electrical Problem

Hey guys, I have recently joined the forum because I am helping a friend out with his 1972 Stingray. We had it running about three years ago and there were no problems, but the car has been on stands and not been started in the past three years.
Here is the problem:
I went to go put the battery in and hooked it up, however the dome light didn't go on. I proceeded thinking that the light or fuse might have been bad. I turn the key but no power what so ever (no accessories, no crank, no horn, nothing).
I have worked on cars and am mechanically inclined but this just baffles me.

P.S.: I checked the leads on the starter and they are fine as well as tight. I did notice a burnt/singed wire but it was getting late so I had no time to investigate. I believe that wire might have been a fusible wire but that is just a guess.

I would love to have this beast out of the garage and on the road again so I can post up some pictures!

I think you answered you own question.. that singed wire is probably the fusable link for power .. or you ve got corroded connections from its sitting for years. check the link , if its good, clean all battery and starter connections and the ground cable to the frame from battery

I will post up a picture of the wire tomorrow. If it is separated, will it be possible for me to solder new wire to the ends of the existing wire?

Also the car is extremely clean so cleaning the terminals would be a little overkill haha. Thank you for confirming my diagnosis. I will get back to you with news of progress!

Fusible links should not be soldered back together. Fusible links should be replaced like in kind. They are there to protect the electrical system from overload. If the wire you suspect is bad you can check it by performing a continuity test on that section of wire/fusible link, this is with the battery disconnected. And welcome to the club!!

Are you sure that all grounds are clean and tight? If you have no power what so ever, I would start with the grounds. Starting with the battery . . .

In addition to all above posts make sure that your battery is fully charged and putting out good voltage and amps. It might have a dead cell or internal short.
