   I jumped the gun.  The voltage meter was on the wrong setting.  I didn't   
   think that the meter was on the wrong setting, because the newer battery   
   that I pulled out of another car happened to test at exactly 12.7 V on   
   that same wrong setting.  What a coincidence.   
      
   I pulled the new battery from a car that slid down my back dirt alley 2   
   weeks ago.  I haven't bothered to pull the car out yet... my come-along   
   isn't enough to pull it out.   
      
   Anyway, that car that slid down, the dirt hillside was in contact with   
   the rocker panel firmly, and I guess that TOTALLY drained that battery.   
     On the correct setting, the new battery just tested at 2.some volts...   
   yikes.   
      
   I have the new battery on a little 1 amp charger now, maybe it will come   
   around by tomorrow.  I was very confused after my first post, when the   
   car would not start at all.  Yep, I guess 2 volts will do that.
