This fuse protects everything except the starter. The OP reverse connected the battery which allowed massive reverse current through the alternator rectifier, which blew the fuse (and maybe damaged the alternator). I think (at least) all of the older CK and DK models have this fuse; it is inline near the starter, probably wrapped in black tape. The fuse is a common automotive item, about $5.
OK, thanks. I was just getting ready to order one myself and then I thought if the alternator is bad then it would save on shipping to order that at the same time. I'm going to spend some time trying to nail down if the alternator is bad. It seems to me if it was bad the tractor wouldn't keep running for hours after I start it.That belt is hard to match up at an auto parts store unless the parts person is good at it. It actually has a metric measurement for length, width, and angle. I was unable to find one from an older Toyota, Nissan, etc., that would match. I just ordered from Michigan Iron and Equipment. a Kioti dealer.
.... Does anyone know a good source for the OEM part or the part No. of one that works? I'd like to eliminate the belt as the problem before I buy a new alternator.
Thanks, that sounds like the most certain way to find out.In case you don't know, there are several excellent, free, dealer-sponsored online parts look-up sites, like this one by MIE (a sponsor). Ignore the "quick parts search" and work through the menus on the left half of the page.
Also, if you remove the alternator and take it in, most auto parts places (e.g. Advanced, Auto Zone, O'Reillys, etc.) will check it for free.
Also, if you Google the alternator Kioti or nameplate part number you'll probably find one for MUCH less than the Kioti dealer price,
