You said: "But which goes where? The white wire has a "R" stamped in the case, and the blue wire has a "F" stamped. (None of the websites mention that). So, which goes where?"
That concerns me a little bit. The 10SI has a wide plug with both terminals flat (lay your hand flat on a table next to each other) while on the earlier alternators the small plug is more square and the terminals are parallel (hold your hands like you are praying) which is the kind of alternator that uses an external regulator.
The 10SI alternator has a "1" and a "2" where the little plug goes into the side. The "1" is the smaller wire (excite, usually white) and the "2" is the larger wire (sense, usually red). The sense wire goes to the post on the back that goes to the battery, the smaller wire goes to the ignition switch either through a light bulb (plug in style side marker lamp will work, don't recall the number), a resistor (22-27 Ohm, 5 Watt minimum) or a diode. Usually the diode is specified to be 6A at 50V but that may be overkill. I use diodes rated 3A and 1000V because that is what I have on hand and it works for me. The band on the diode goes toward the alternator.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
