Hi all...
My misses has an AU Falcon. It runs good but when you put the electric windows up or down it makes the revs drop down real low like its going to stall.
Any suggestions on why this could happen.
My guess would be that the alternator is on the way out and cannot cope with the extra power to supply both the electric windows and spark to the motor.
Although it doesn't do it when the head lights are on.

:
Any suggestions please???
Cheers.
