regulator wire color

[1972XlchBobber]

I have a newer style solid state regulator.  The connector is cut off and I have three wires that are sun faded:

Green
Red
Orange

Although the colors could be faded something close to these.

Can anyone tell me which wire is which?
I guess I have:
Field
Alternator
Battery

Thanks, Mike

Could it be Tan rather than Red?

Orange -  B  (Battery)

Tan -   A  (Armature)

Green -  F  (Field)

green- Field
Red  -  Batt.
Tan or orange- Arm.
I have one of each. Greens and reds in same position. Orange on one  tan on the other.
