my starter went out and so we changed it and took it up to the parts store and had them test it and it was still good. so we did the same with the battery and that was bad so we changed that and we changed the starter solenoid and the ignition switch and when we tried to crank the truck we got sparks at the solenoid and nothing else we lost all power to the headlights and the cab lights went off and when they came back on they were barley bright enough to notice. does anyone know wat the problem is and a way to fix it?

There has to be a bad connection at the solenoid. Remove the wires and clean very good.
