Hmm... I found the following quote from an old thread: http://forums.s2ki.com/forums/showthread.p...ernator+current

I believe MacGyver is also an EE.

He did say he was not getting into electro motive force discussions... (I wonder why...)

As the overall electrical load increases more current flows thru the alternator rotor field coil, which in turn makes it harder to turn. Thus more power is "robbed" from the engine.

This is just the first law of thermodynamics at work, aka "there is no such a thing as a free lunch".

HID are notorious for their low energy consumption. They won't draw more than 3-4 amps per bulb when running, in-rush current is probably double that or a bit more when starting.

Just out of curiosity, I remember reading somewhere that the cost of implementing daylight running lights in the USA was close to a billion dollars a year just in fuel costs!

this thread is really kinda past its life span. lol. lots of dyno days have been done with ap1s and ap2s. if you do a search for dyno day, you should find plenty of what you are looking for.
