With the original 6 volt generator, the light switch was a combination light switch/generator charge control.
The 4 positions are: L - Low charge, lights off H - High charge, lights off D - High charge, front lights on dim, rear light on bright H - High charge, all lights on bright.
With a 12 volt conversion, the switch L and H positions serve no purpose - they become simply two alternate "off" positions for the lights.
If memory serves, power supply to the light switch goes to the terminal #1 (bottom of the fuse holder). Rear light should be wired to terminal #2; the front lights to terminal #3.

Incidentally if your alternator is operating correctly and the battery is good, the charge rate should taper to 2 - 3 amps a few minutes after the engine was started. However if the ammeter continually remains pegged it means the battery is being overcharged. Best look into it before the battery gets boiled dry!

Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
