1989 Chevy S-10 no power

Hello, if the battery has a full charge and the cables are clean and tight on both ends, you might check any circuit that gets ignition feed. That feed comes from the ignition switch. There is ignition feed to the clutch switch, yellow wire, goes hot with the key in the crank position. The purple wire from the clutch switch carries voltage to the starter solenoid, goes hot when the clutch switch is activated.
