I recently became the proud owner of a late '60s JD 1020 diesel. It's a really great little tractor and gives me all of the muscle I need to bush hog and clean up the 150 acre tobacco/soon to be timber farm my wife recently inherited in Southern Virginia.
Since I purchased the tractor I've changed the oil and oil/fuel filters, and put a fresh coat of paint on a number of parts. It works great, except that the battery doesn't seem to be getting a charge from the alternator (the alternator light is on and I have to charge the battery before each use).
I purchased a new alternator that is supposed to be a universal fit for JD tractors, but when I went to install it the other day, the leads on the old and new unit didn't match, so I wanted to consult the experts before I screw something up.
Below is a link to a picture of the new and old alternator.

If I were the guessing type I'd say all of the positive leads go on the big terminal and the negative goes to the little terminal, but I'd love confirmation before I wire it up.
