3000 Gasser generator rating

What is the amperage rating on the original generator of a
3000 gas engine tractor? I stuck a cab on mine and want to make
sure I don't overload the generator with lights and heater fan, etc.
I'm planning to use LED cab lights, so that should reduce load some.
It has front and rear wipers too so I figured a little math was in order.
 
Try not to run it past 80% of it's rated capacity for long durations. In other words, extended running at 18+ amps will severly
shorten it's life.
 
See if this sounds right to you guys.
I've got the two headlights, about 3 amps each.
Two cab mounted LED headlights, 2.25 amps each.
One rear mounted LED work light. 2.25 amps.
Two stop/turn/tail lamps that I have to estimate.
Even with them on and the flasher portion running,
maybe an amp? That would put me at 13.75.

The headlights and tail lights are on the original switch.
The cab mounted head lights as a pair on another switch.
Work light on it's own switch. The flasher portion of the
tail lights on another switch.
Well under the rating even if I had them all on, which I
doubt will be needed very often.

But, add the wiper motors. I don't have any rating on those.
The best I could find was a diagram that said to use a 7-10A
fuse for two. Assuming 75% of 10A, that would make it tight.

Then there's that heated defroster fan.
Hmmm, better turn some lights off if I need to run it.
