Mazda Repair: Alternator light, diods, mazda 626

Question
I have an Mazda 626 2.0 Liter 4 Cyl manual transmision when i turn on air conditioned the Battery or alternator light come on and remain on until turn off car, the alternator operation its normal.

Answer
Hi Kacques, thanks for asking
this still sounds like a problem with the alternator, the diods may be gone or even the voltage regulator, when there is a big draw on the chargings system, the alternator efficeny drops to under a minumum charging specification. wich in this case sets the battery light off, I recomend that u get an AVR test done on this car before going into an alternator, there can be a problem with the battery as well.
Good luck
