Hy Chevy61, on the starter there are two small terminals on the solenoid, the one next to the engine block activates the starter, the terminal on the outside is the power feed to the coil when the engine is being cranked to start. That wire is the wire for the resistor bypass circuit, that wire should run from the solenoid terminal to either the output terminal of the ballast resistor (mounted on the firewall most likely) or to the coil positive terminal. This circuit provides twelve volts to the coil when cranking the engine to start it, giving the engine the best spark. Other than that you could have distributor issues, cracked distributor cap, bad condensor, bad rotor, bad distributor cap, bad wires. Hope that helps.
