Question about 2006 Chevrolet Trailblazer
Alternator needs good battery to keep SCR in the regulator on if it is loaded it will shut down. this will happen when you try rolling window down or rear defog will load up the system. When the truck is running and battery is hooked up the vehicle should run at @700 RPM at idle and when A/C compressor is commended on it should idle up to @1000 RPM and then back down to @700 RPM when compressor cycle off again. But if the system almost stalls then the battery and alternator should be changed together, A bad battery will damage a new alternator and a bad alternator will damage a new battery.
