My discharge light is on and the ammeter shows a discharge condition which 
increase significantly when the headlights are activated.  I want to make sure 
that it is my generator and not voltage regulator.  I'm not sure how to check 
the generator but I took a reading while the car was running of a little more 
than 3 volts off both the large and small terminals on the generator with the 
volt meter's other wire going to ground.  What should the voltage be?  I was 
expecting 13+ volts.  Does this mean my generator is trash?
Thanks for any advice.
