Question
Hi...I have a 64 Fairlane with a 289 and changed the generator.  But, I haven't hooked up the two small wires yet because they are both white and I lost track of which went to which post.  I did connect the large yellow wire.  One of the small white wires goes to the outside of the voltage regulator and is the only wire that connects on that side.  The other small white wire joins some other wires and goes to the inside of the voltage regulator, where there are three separate connections. Which posts do I hook each of these wires to?  The wiring diagrams say that the right post (me facing the car) is ground and should have a black or red wire but unfortunately it's white.  I guess the real question is what side of the voltage regulator does that ground go to?

Answer
Unfortunately it appears that some one has rewired the car or parts of the system and not used the factory color code. The terminal on the end of the generator is the output and it is connected to to the "A" terminal of the regulator. The two side terminals on the generator should be marked near them. One is "F" or field and connects to the "F" terminal of the regulator, while the "G" terminal, or ground, is connected to one of the mounting screws for the regulator and grounded to the cars body or frame.
