I have a 70 coupe 351w. i replace the battery, solenoid, and checked the ground on the engine. The starter won't crank nor is there any power to any lights on the car. Every once in a while, the car will get power, but if I try to start it, I loose all power. Don't think it is the starter switch, but I don't know if there is a fusable link anywhere that would cause this. Any thoughts?
