In theory they look like parallel circuits, so I don't know what difference it would make, but then I don't grasp all the mysteries of what all happens in the internals of a regulator, either. I'd try the simple step of switching the lead for the lights over to the L terminal first see if that fixes it before I got into the third brush.
Follow the link to the very useful page, bookmark it, then have a look at #2 and #6.
The difference that it makes is that any loads connected to load terminal will receive generator current directly from the generator without the regulators current sensing circuits knowing anything about it. In other words the current regulator function will ONLY apply to the generator current going into the battery, totally independent of any loads being supplied via the L (load) terminal. Imagine a lighting load so large that the lighting current plus the battery charging current is so large when combined that it exceeds the regulators current limit. If those loads are connected to the battery, this combined load is the way the regulator senses and controls generator maximum current & would cut back on field current & thus generator output to stay within the design current limit. However, when those lighting loads are connected to the load terminal, the regulators current sensing function does NOT see that current, rather it sees only the current applied toward re-charging the battery and allows the generator to do its best to support both loads.
The scheme appears to do nothing to protect the generator from current overload, which may be why it fell from grace over the years.

Today's Featured Article - The Great Escape - by Dave Hollrah. It all began Monday with a little baling of second crop on the lake shore field, and as I drove out past my sister and her hubby's place, this small calling sound could be heard from the general direction of their manure pile. 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
