It's not a design rule (how can you make a design rule about that ?) it's a traffic law, and yes it used to be the case, no idea if it still is - certainly no-one seems to get booked for it in Sydney. > Pity that Shane and Spooky from the Highway patrol aren't in this newsgroup > any more, they could shed light on this subject No, I'm sorry, that's not even vaguely a pity, more like a cause for celebration JL

The torque required to turn the shaft of the alternator is related to the load of the current. So when more current is produced the harder the engine works to turn the alternator. G-S

It produces electricity based on load demand (modified by the actual battery capacity and storage and the generators 'size'). G-S
