get a clicking noise when starting

My van need jumped the other day and it started right up. I left it run for about an hour and everything seemed to be ok then. It would turn over but sounded kind of tired. Well yesterday I went for about a 250 mile ride and when I stopped. It wouldnt turn over all I got was a clicking noise. I got it jumped again and it started right up. Well then the next time I shut it off. It wouldn't start again. When i checked the engine with a voltmeter well running it was at around 14 volts. When I shut it off right after it has been running it is around 12 volts. After it is off for awhile it goes down to between 8 and 9.5 volts. I checked the drain on it off the negative terminal and it is around .04 amps. Also sometimes the speedometer and tachometer wont work when I start it up, and sometimes when i turn left the emergency brake light goes on. Any help with any of this would be greatly appreciated.

go to sears and see if they can test the battery out. sounds like the battery is dead.

Sounds to me as if the battery is not taking a charge when you are driving it. Have you cleaned the terminals lately? Even if they look good you can't alway see the carosion. If that isn't it have the generator checked, than the altenator. There must be something that is not allowing the battery to charge.
