Driving in this morning I was beating on the steering wheel to favorite tunes when my FJ60 idled waaaaaaaay down, the charge light came on and she started spitting and sputtering ???
Just don't do that very long, the alternator (if it is good) will max out and can go bad.

She likes to be petted. No beat.
With the engine running pull off a battery cable. A charging system will keep running without the batt.

I know she hates it when I beat on her
ran well at lunch, maybe yesterdays fill up or the 95 degree temps got her feeling down (vapor lock, bad gas???) all is well at 211,000 miles - she's barely broken in

Without the battery the net draw on the alternator is less, not more. Otherwise the battery wouldn't be getting a charge.

The load is less, but the alternator sees it as an open and will try to compensate. I did this and measured significant increases in voltage and current output from the alternator. A mechanic buddy told me about the issue, so I hope I have my facts straight. My alternator ended up being good, I had other issues. IIRC bad/correded connections.
