I noticed today that the Deuce cranked a little slower than usual but just thought it was because it was a bit cooler out last night than normal. However, by the time I drove it to work (couldn't resist

) the voltage gauge was deep in the yellow.
After work I went back out and the voltage gauge had risen to a bit below the green (my Deuce has the tiny little solar panel on the hood with a little controller down in the battery box that says "Solargizer" on it, maybe it charged the batteries a little bit?), but when I hit the starter she turned over slowly but managed to fire. I drove it home (thank God for mechanical diesels) and pulled the batteries out and am charging them now - the alternator is definitely not charging.
Hopefully I will have some time on Sunday to reinstall the charged batteries, fire the Deuce back up and get to troubleshooting with my multimeter. Anyone know where I could find a rebuild kit for the alternator? As long as there aren't any specialty tools required, since the documentation is good I may just rebuild it myself if I can get the parts if needed.
