88 camry charging problems
 

Hi, everyone. My dad has an 88 camry, it runs well, but it won't charge the battery. He checked all the wiring-it's in good shape, so is the battery, but it seems to be the alternator. He replaced it with a delco, or a similarly-priced brand. Is there a good brand out there? Or, which new models are good? Thanks in advance
