Being the joker that I am, I'm tempted to answer "Yes" and let you stew. But, as you are new I won't.
First, you need to acquaint yourself with the
1981 Electrical & Vacuum Troubleshooting Manual. That breaks the wiring down into systems and explains how to test it.
Then, turn to the
Fuse Block & Circuit Protection section and see if that helps.
As said in the New Members section, we have a large reference website to provide support.
