I build and sell electronic regulators too, and have, of course, used one on my Brum, as on my other mc’s, for years. Generally they provide far better service, but be sure to build in a fuse. I use the measure that I allways drive with lights on, and rarely look after the water in the cells.
Hello Jan, if you are in a position to supply voltage regulators for Scotts perhaps you could put a note in the “Sources of Supply” feature so that members might be aware of this. Best wishes, Jeff Reed.
