hey i just got my new engine last night and threw it in. The question i have is that on the old alternator or generator(i'm assuming its a generator due the the different diameter from front to back)has a plug labeled D+ and a B+. The new engine i picked up has a alternator which has a D+ and a DF. I believe the F means field but not sure how to hook it up. Being a newenginei don'twant to take any chances.

what type alternator is it? #, if it has a built in regulator then take your old one out. I recently upgraded to an alternator recently and simply followed the wire to my starter, and another to my ignition. It depends also where your regulator was mounted, if its under the seat your gonna have to re-do the connections there. Just follow the wires back or get a wiring diagram and it should be a piece of cake, although follow Stan's advice.

I'll have to check out the wiring on mine to tell you which wire connects to the DF, but let me know if what type of alternator were dealing with.

Here are a few old threads that may help.

Bosch AL-82 (X or N) has the built in regualtor.
Bosch AL-78 has the 3 prong plug in on the alt and regulator under the rear seat
Generators 6V has reg on top...12V under rear seat. When you switch to the AL 82 you bypass the regulator.
