Hi all. I just purchased a Craftsman mower off craigslist for cheap... Got tired of working on the piece of junk I had before... Well this one's a lemon as well. Got it home and mowed for about 10 minutes and it just quit. Keeps Blowing Fuses.

So, I've looked it over for bad wires, did a few minor repairs and noticed a bit of melt on the 2-prong connector under the engine... Somehow attatched to the pulley (?) I'm wondering if this could have something to do with it... Also, what is this part? Stator? Clutch? I did notice a bit of a squealing noise coming from that vicinity when I bought it...

By the way, it's a riding mower with a Kohler 18.5 hp engine.

How do I check this part?
