I had a 3 year old battery that was leaking acid. I replaced it. 3 weeks later I noticed when starting the truck one day it just made a clicking sound but when I cycled the ignition switch, it started. It did it again about a week later, but again started after a second try.
A week after that it just went click. The battery indicates 12.66 volts, but the voltmeter on the dash shows about 9.5. The headlights are bright, all the elec accessories work well. There are 3 wires coming off the positive side of the battery. Which one does the dash voltmeter read from? If it reads from the cable that runs the starter that would make sense that everything is getting power from the batt except the starter.

The best place to start is by the battery, take the battery out and wash down the old battery acid. Check all the cables on both the positive side and the negative side. Even though most cables are covered in plastic if battery acid gets into them they can make for a bad connection without you even seeing it. Check and clean the cables good.
