УАЗ Патриот. Если плохо крутит стартер. Все расклады и что делать!?

So, out of the blue, the starter on your UAZ Patriot has started cranking poorly. Everything was fine yesterday, but today the battery is cranking the starter with great difficulty. It's fine in the morning, but when hot, it won't turn at all. The first thing you need to do is watch this video. This will prevent you from wasting a significant amount of money. There could be several possible causes, and I'll break them down so you can easily determine where to look and what to buy.
