I am looking for a Schematic on a variable voltage regulator for an alternator,I have posted on two or three message boards but so far no one has been able to help other than to suggest that I buy an allready built regulator!...I don't want to buy a already built regulator !....I just need the schematic and I will build it myself...I have a heavy duty Leece-Neville alternator and I want to add it to my existing system so I need to be able to run two alternators and be able to control the voltage on the Leece-Neville alternator from say 10 volts up to maybe 18-20 volts DC.......can anyone tell me where I can get a copy of the schematic of a Variable voltage regulator circuit?

I am also looking for a schematic/circuit diagram for a single final output transistor using a 2sc2290 or maybe a SD1446...I saw one that someone had tried to hook up on the inside back of the radio case but it was a crude job and it didn't look all that good........

And the last thing that I need help on is a web link to or construction plans on building a homemade 5 to 10 KW, 50 Ohm Dummy load...either oil filled or water cooled.I have been searching Google but haven't had a lot of luck, anyone got any ideas ?

Just post your answers here and I will check back often to see if anyone can help Thanks,Dr.BoGator
