Ok, finally did the right thing and called minkota. After being told by parts they don’t sell this part and you just have to trash your old charger I got frustrated. Smoked a ciggarette and decided to call tech support to find out how to repair. Low and behold they do sell the repair kit with temp sensor installed. So if you have a 220D or 330D here is part number.
2883225 price is 21.99
Hope this helps you guys and yes it should come with instructions
