MG TDs didn't come from the factory with an alternator to recharge the battery. In 1952, an old generator was good enough. In fact, it was probably still good enough in 2019, but in that year, Jake Roulstone and I collaborated on a blog post on how to convert to a modern alternator, which became Part 45 of the Beck TD saga. The installation documented there has worked perfectly ever since, so of course this winter I decided to redo it. What good is a project car if you don't have projects!
