When my starter started going, it would just "click" and not crank. That single "click" was the solenoid plunger doing it's thing, but the copper contacts inside had worn out, not contacting properly. They usually last for about 100,000 miles.
Pic1= Remove starter.
Remove end cover from solenoid and plunger will just tip out.
Pic2= Solenoid plunger before.
Pic3= After wire brushing solenoid contact ring. Do not use a file. It's just copper.
Pic4= New contacts seen here.
Pic5= New ones in place.
Pic6= Old contacts. Note the wear, prohibiting complete contact for the circuit to be made.
Pic7= Solenoid piggy-backs on starter. Reconnect positive output from solenoid to starter motor.
Pic8= Plunger (with spring) about to go in.
Pic9= Replace solenoid cover.
You are now good for another 100,000 miles.
