Headlight switch amperage?

["Kurt Schmidt" <schmidt_kurt@hotmail.com>]

I have a 75B and have noticed that the on/off switch gets quite warm
The wiring allows all of the current (a lot) through the switch so the
fact that the switch gets warm does not surprise me too much...

How much current do others have going through the _brown_ wire feeding 
the switch when the parking lights are on and when the headlights are
on as well?  

I think I might be grounding out somewhere but I'd like to be sure...
