light coming on saying charging system and battery light came on

Asked by Aug 21, 2019 at 04:08 PM about the 2009 Chevrolet Impala

Question type: General

we changed the alternator and it isn't staying running the battery light came on and it says charging system

1 Answer


Make sure battery has a full charge and battery cables/connections all good? If battery is down, get charged up, can't do any testing if battery is down? Check for applicable trouble codes relating to battery and charging system? The diagram is for generator. I see at least two fuses and fusible link you can check? Use a test light at generator bat terminal, hot all the time, even with key off. If no voltage, something wrong with wiring circuit--fusible link or fuse? Now, the battery current sensor should be on battery cable, either positive or negative? I can't be positive that replacing any component will fix?
