Which one is A and F on Generator?

When I am looking at my 62 FLH, 6 volt generator from the front of the motorcycle, which is the A terminal and which is the F terminal? There is an upper terminal and a lower terminal, I think someone hooked up generator wrong.

Normally, the generator case has an F and an A marked on it. Not on yours? On mine, the F terminal is the one that is further forward.

F = Field = Foreward, A = Armature = Aft. or Closest to motor is A - Armature, closest to front of frame is F - Field. A goes to Relay, F goes to switch.

According to my Info, Hauula is correct-and this holds for the following generators:
Model 32E 6V 2-brush Standard
Model 32E2R 6V 2-brush Radio
Model 48 6V 3-brush fan-cooled Heavy-duty
Model 48 6V 2-brush fan-cooled Heavy-duty
Model 51 6V 2-brush fan-cooled Radio
Model 52 6V 3-brush fan-cooled Standard
Model 58 6V 2-brush
Model 61 6V 2-brush
Model 64 12V 2-brush
Model 65 12V 2-brush

In 1966, the terminals were reversed on the Model 65A 12V 2-brush

Well, I just copied the info from the service manuals-it could be in error.

For info on pole positions... HD Service Bulletin #521 (October 11, 1965)

"The 1966 generator used on E-Glides and Sportsters has the positions of the positive and negative brush holders reversed so that when the generator is mounted the positive brush will be toward the top instead of the bottom. This was done to protect the positive brush holder from accumulated moisture and possible grounding of the positive brush holder."

And a bit more...

"All 1966 generators have a plastic coated brush cover strap to protect brush holder and commutator from dirt and water."

1965 (Model 65) and 1964 (Model 64) the A terminal to the bottom; 1966 (Model 65A) the A terminal is on top.

My 65 pan is a 5 digit vin number so was a late production. The generator is stamped "Model 65 - 12 Volt"" but has the A terminal on top.
