[AT] Was AT Digest, Vol 88, Issue 17, Now 6 to 12 Volt

[Mike Sloane]

There are several reasons for higher voltage. One obvious one for car 
manufacturers is that they can use smaller wires as the voltage goes up, 
saving money on copper as well as weight. I have heard that Mercedes 
Benz is experimenting with 48 volt systems for cars.

The rumor about the parking lights in London is true, but the cars were 
equipped with very small parking lights that hardly used any power. But 
there is no doubt that you can get brighter lights and better starting 
motors using 12 volts than with 6 volts. As you probably know, some 
tractors use 24 volt systems even back in the latter part of the last 
century.
