MAD ELECTRICAL?

The reason I bought the resistor up was that in the wiring diagram it shows wire R5 from ignition side of regulator to resistor, and J2 and J3 from resistor to ignition switch. The ignition system doesn't need the resistor. There are only two wires on back of alternator, battery and field. Thanks for your input.. I think I am going to ask the resistor question in the early "A" body forum..
