And the amount of fuel a pump "guesses" is being transferred compared to the actual amount of fuel being transferred will vary
dependent on a number of factors. Temperature being one.

And some people said they were just pre-programmed responses unaffected by
actual conditions.
It looks like those people may've been right eh?

OK so we've proved that it's auto-compensating for any extra load
(explaining why you don't get an idle-drop when the headlights are switched
on) but the jury's still out on whether it's really measuring
fuel-consumption or just smart-enough to know that aircon raises the usage
by a pre-set amount.

Nev, next test is to run the computer in diagnostic mode with the air-con on
and then cut the aircon-compressor belt and see if the readout changes.....
if it's not too much trouble!

I have no knowledge of angular force and that engineering stuff you were
talking about so I'm more than happy to accept your word that Andrew has
stumbled upon a serendipitous truism, John.
That doesn't change the simple "will the alternator require more energy to
turn" question though.

I just stick to the simple things that I DO understand (and if I can't
follow what you're saying then I'm very confident that there's not one
chance-in-hell that cowpat-for-brains Atec is ever gonna!)

And this is exactly the difference in style of comment between someone
like Dales father and Hammo...

Crystal but _still_ an irrelevant red herring.

The point under discussion isn't if the fuel used is wasted or not...
the point is 'is there fuel being used' to run the lights, and some
people seem to be in denial about the fact that there is.

Others like you seem content to throw odd, technically correct but
totally useless and irrelevant comments into the conversation.

You didn't perhaps work for Microsoft in a past life did you? :)
