I agree fully! I've been through 19 alternaters! About 12 of them or so were through Autozone. A some others were high amp alternaters and 1 Nissan, and the other is from O'Reilly Auto Parts. I'm having problems with this O'Reilly Alternater. It's weird, at night time, with lights on the voltage will drop to 12.9 and it'll have just the battery light fade in and out when you go past 3,000rpm or 4,000rpm.

Thats not a good thing. :eek:

19 alternators? Sounds like you have a serious electrical problem. I had something similar with my starter. I went through about 4 of them then finally got it fixed. Still on my original alternator though.

Yes, I agree it depends on what alternater you buy. I'm going to try to get my starter with a different company than Autozone. I'm currently having issues once every week or so with the car not starting. First law in my book, no autozone replacements for electrical parts. Second law, get nissan quality parts. (Unless it's performance stuff.)

Anyone know how to make the SR20DE Alternater fit onto the GA16DE? I heard from some alternater shops that these are interchangeable with little modifications. Is there an engineer out there that can sell brackets for us GA guys? I'd be willing to buy one, it's worth the money. (not too much though, still gotta pay for gas money & food :) )

I read heard that the SR's alternaters put out 10-30 amps more power than the GA depending on the actual unit. That would give me a little bit of head room for nighttime. With all the accessories on at idle (night), the voltage drops to 12.6-12.8. With all the acessories off at idle (day), the voltage stays between 14.4-15.5.
