Electrical problem
2006 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 70.000 miles

When idiling or at a stop light the voltage on the meter drops to 10 amps then when I take off and on the road it goes to about 14 amps. I do not have any problems starting the car.

Best check the charging system it shouldn't do that-should be 13.5 and above-inspect belt tension.
