Blue to F, White to R F stands for field. Voltage on the field determines how much output from the alternator. The regulator varies the voltage on this wire to keep the system at more or less 14 volts output.

What is R and F on a alternator?

The R and F terminals are the Reference or voltage sense terminal and the Field terminal. The color on the spade connectors doesnt matter, you will have to use a multimeter to determine which connector goes to which pin. The R will be hot at all times while the F will only be hot when the ignition is keyed on.

What does F stand for on a voltage regulator?

F=field terminal, simply a wire going from the F terminal to the field terminal of the alternator. The regulator varies the voltage on this wire, and that varies the output of the alternator.

What is D on alternator?

D- is the battery negative connection. I do not know what you are hoping to achieve. To carry out a meaningful test you need a voltmeter to measure the output volts an ammeter to measure the output current and a means of applying a appropriate load to the alternator.
