Have battery load tested. Check all terminal & terminal wires for corrosion or burns or frayed wires and make sure all are connected tight. Check all ground wires from engine block to frame and frame to battery. Check all fuses under hood and dash. If all those are good have alternator tested and starter. Look for shorted wires.
