[Roger/Sacramento]

I have a stock 12V starter in the pickup that is not new but, has been working just fine. On trying to start the motor all I got was a click. I disconnected the vehicle battery cable and jumped the starter with a spare battery. No response. I took it out and removed the armature. The brushes are like new and there is no visible evidence of anything wrong. What usually happens in this case? Does Napa have the parts needed?
