Default AU Flat Battery syndrome

Has anybody had a flat battery effect when the car gets to running temperature? The engine appears to charge perfectly when its cold and then tapers off and on when at proper running temperature. I ahve changed the alternator, starter motor, battery and have increased the number of earth straps etc. The problem won't go away and I am stumped at what it could be.
Any help would be appreciated. :eclipsee_

Ive only noticed that with the AC running, the volt guage drops off a bit, but then goes up to normal when AC is off.
Still running original alternator, have changed battery over a year ago.

Thanks for that. I seem to still have the problem even when the AC is off (but not as often).

Can't say I have had this issue with mine .... but with no voltmeter to check things I can't say. Although I do run a lot of electrics in the work ute ... I did get one flat battery (as it is factory LPG ... starting can take a lot out of it).

But I fixed that problem and am running a Optima Yellow Top deep cycle battery.

had a similar problem, alternator would over-charge the battery and killed it. battery would then not hold a charge. took it to an auto electrician. He changed some circuit in the alternator or to do with the charge (not to sure) for $130.00 and problem solved.
