Well, there could be a short.  I am just wondering if the lights are 
being powered by the genny, but the ammeter is confused because my 
wiring is simply confused...  and you are right, the lights are the same 
as on the M's.

I may have confused you, though, now that I think about it.  When I said 
full discharge, I meant that that ammeter looks the same as if I turn on 
the lights when the tractor is not running.  So the discharge is not 
more than normal... and I am sorry that I confused you.

Is there any way that I could have screwed with the wiring enough to 
allow the genny to power the lights, but the ammeter to think that the 
battery is powering the lights?
