Pete
My understanding of it is that under normal driving conditions the battery is sustained at a level to supply all consumables (not 100% charged)and it will only start charging on overrun. Thus not taking power from the engine while accelerating and reducing fuel consumption. ether that or it's just designed to p!$$ us off.
Andy, cheers
