My GMC envoy had a battery light on and the battery Gage was low. Battery tested good. Alternator tested bad. Changed alternator and now the driver information center tells me that the battery is not charging but the volts are reading good on the Gage. Had both tested again and they are doing the job but still have battery light on and information center says battery not charging. Can anyone tell me why please?
