My Taurus fan is steady @ 18-20 amps while running. I also have the electric fuel pump, stereo etc but i did upgrade the wiring to the ammeter and also have the same guage wire going directly from the alt. to the starter relay with a fusable link. still shows a reading one the ammeter but isnt forcing all of the draw through the meter.
Also i updated my 60 amp alt to the 78 amp from NAPA for the 1985 and up LA motors.... works awesome. Noticable improvement at idle...
