Arnt alternators AC?
If so, when you rectify the signal to DC, you should be able to fiddle with the waves to make 12V..... Have a look at voltage regulation and
rectifier ICs on RS.....

The later Beechcraft Bonanza ran a 24 volt alternator and electrical system, yet had a 12 volt cigarette lighter output, so I guess it's
possible.

Cheers Tegwin... I've got my hands on a teeny-wee alternator off a Cosworth F1 engine and thought I'd try amd make use of it (if
possible).

Alternativley....
Could you do something very simple..
Get a pair of small 12V batteries in series.... Connect the +ve and -ve at either end onto the 24V alternator...
And then tap off 12V from each battery... (Worth noting that would technically give toy plus12v and Minus12v)
No idea if that would work..... but might do..

^^^ no - too risky plus you'd want to load upthe batteries to charge/duscharge at same rate - for example left hand light to 12 V and RH ligths
to -12 V.
sooner or letter you'd short out on of the batteries.
the alternator throws out AC but the voltage is determined by construction.
you should be able to fit a rectifier and 12 V regulator but ensure that they can handle the higher voltage of the alternator.

Will take it into my local motor-sparks and see what they say... probably, 'computer says no', but worth a try as the thing just weighs a
kilo

Why? Are you going to be able to get spares or an exchange/new unit when it goes wrong?
