If anybody wants further context, here's an excellent paper on the status of the Voyager mission as of 2016, written by one of the engineers at JPL. It has an overview of what all the instruments on Voyager do and everything the team had done to keep the mission going as of that point. https://csclub.uwaterloo.ca/~pbarfuss/VIMChallenges.pdf I also highly recommend the documentary "It's Quieter in the Twilight" which is about the entire Voyager team and their efforts to keep the program operational.
