I'm converting a 630 from 2 lamp to 4 lamp. (Fender conversion too of course from tear drop to flat top) Some time ago Buick and Deere said the 4 lamp, when dimmed, uses the "automotive" method of 2 flood lamps energized and long range spot lamps de-energized. Looking at the wiring charts on page 80-5-23 of JD Service Manual SM-2029, it doesn't show a dimming resistor for 4 lamps. So is there no "true" dimming function for 4 lamps? Is the ignition/light switch the same part number for either 2 lamp or 4 lamp? Looking at the manual diagram, it appears that all 4 lamps are never all on at the same time. Which set are called "floods" and which are "long range spots" with reference to their position of inner or outer on the fender? Is the manual diagram totally correct? Are the glass lenses different for flood and spot?
I haven't been around a 4 lamp set up so I'm "in the dark" concerning them. Just want to be sure I understand the intent of the design. Any further explanation beyond the questions I've asked would be most welcome.
