GM likes to tap off the large starter terminal with fuse link wires that feed other systems. Start by looking there and tugging on them. If they act like a wire, they're okay. If they act like a rubber band, they're burned open. More commonly you'll find a wire corroded off. The best repair technique if a wire is broken right by the terminal is to install a new crimp-on style terminal, solder it too for the best connection, then seal it with a piece of heat-shrink tubing.
