My 92 4wd pickup truck has 110k miles. I notice at night when coming to a stop that the lights willl dim down. I have a new battery and new belts all around. I am sure the belts are not slipping. I have also noticed that the charge indicator on the dash will stay on the charge side but it does come down when I see the lights dimming. Should I be concerned about the alternator failing? Thanks for any input!
