@repowel - alright, I have to admit when I read your post last night I thought you were full of it... "a wire that carries full voltage but no amps" that's just silly talk... So, well, um... You are a genius!
This am I started at it again... And I figured I'd do exactly what jinmans last post suggested (even before I saw it)... And I started at the fuse. Well, hang on, what's this right under the fuse, on about 1/2" pigtail... Ahhh, yes, the joys of owning a very slightly used tractor. A SPLICE! Never would have seen it except I had pulled the side of the fuse clip that's not on the bus bar down and out to trace the wire... A friggin splice! Suddenly, I thought of repowel's post and blushed a little... Could it be?
Tested the voltage and it was fine, flipped to amps on the meter... Nary a flicker. Another round of WTF expletives in the barn... But hope. So, grabbed the small alligator clip testing wire rig thing, went over the splice directly to the switch (30) and the glory of angles shown upon me... Well, really just headlights, but it it is Christmas...
I'll be damned...
There is such a thing a a wire that passes voltage but no amps...
Thanks all... Again through the miracles of the interwebs, community farming is still possible in 2011.
I love you guys... In a completely manly tractor talk sort of way!
