Rich - everything you say about the battery switch in the stock J/30 configuration sounds right. Regarding the effect of the switch with the battery charging - it depends on how it was wired. You'd need to check a schematic or hand-over-hand the wiring to figure it out. The charger may have been wired directly to the battery, or at the battery switch. If wired at the battery switch it could be disconnected from the battery, and the battery switch would determine what batteries were charged.
