The charging system is controlled by the vehicle's computer. Lets assume the battery & alternator is good because you replaced them. Next, is the wiring to the alternator. Disconnect the electrical wiring connector at the alternator and make sure both wires (not the large red cable) are not broken. Either wire is brake were the wires run into the main wiring harness. Give each wire a tug away from the main harness and make sure were the two wires go into the connector are not broken.
