The second way is to use a competition switch (pictured above) which incorporates two pairs of terminals as well as the main battery lead terminals. One of these pairs of contacts opens when you turn off the switch and kills the engine by either interrupting the ignition supply (petrol) or closing the fuel solenoid (diesel). The second pair of contacts closes when the switch is turned off and this diverts the power from the alternator (which is still producing power until it stops turning) and diverts this power through a ballast resistor to earth thereby protecting the alternator.
If you have accessories which require a permanent feed (radio, alarm etc) you can run an aux fuse box direct from the battery to power these items.
Both these switches are available from car accessory shops, motor-factors, race/rally specialists etc, the basic one is about £10 and the competition one is about £22 (both include 1 key but spares are only about £1 to buy). Some online suppliers include the following
