Follow the two smaller battery wires to the body and to the under-hood fuse box where they're bolted on. Make sure those bolts are tight. Use a test light to check for voltage at the larger starter terminal. GM likes to use that as a tie point for other circuits to tap off from. Also test for voltage at the generator's output terminal.
