>>>The fusebox (or at least parts of it) are switched.   But you're 
right--if the component in question is hooked to an unswitched portion of the 
fusebox, or the ammeter, or the battery itself, effectively there is no 
difference, other than the fact that the ammeter would read incorrectly depending on 
which of the sources you chose.

Would a headlight circuit have a power draw when the lights are switched 
off?   I find that unlikely.   My recollection is that the stock headlights 
(not the motor) are hooked to an unswitched circuit on the fusebox, so that 
when you activate the headlight switch with the ignition off, all the lights 
illuminate, but the buckets stay down so the headlights illuminate the inside 
of the fenders.

Assuming that's true, then I (a fellow who asks far more electrical 
questions than he answers, a reflection of my minimal knowledge of the subject) 
feel there is nothing that prevents you from hooking your new headlights to an 
unswitched 12V source--the back side of the ammeter would be best.

True?
