Question about 2004 Chevrolet TrailBlazer
Normally when the alternator is downpowered for any reason(fails) and all thats left is battery voltage /power, you get the light..take the car to a local autozone or advance store and they will test the system for free..or you can start the car and put a voltmeter on it and see what it reads..should show at least 14.5 volts, if not then its replacement time..good luck
