A sort of follow up.
Last Sept was my first time repairing an alternator (from a JD 4020 diesel) after asking for some ideas here (maybe I asked on the JD forum?) The problem was a bad regulator which I replaced and then the alternator charged good. Keep in mind this is a tractor that is NOT used for any work of any kind. It only sits in an unheated building with other tractors and vehicles. (But it has been on tractor rides a few years back) So it sat since last Sept with maybe only 2 or 3 times being started in warm fall weather (no trying to start in cold weather - as this is MN) and this spring at the first start, it didn't charge so I had the alternator tested on a NAPA setup and it tested good - puzzled and thinking I took the alternator and it's bracket to the engine block off and cleaned it all good (paint, rust, and heavy dust) put it all back together and it charges - Thank you Lord - so this is just a further note for what to check when there is a puzzling NO CHARGE from your work.
Sorry I didn't mean to write a book, but this was interesting to me and I thought others might like it too.
