mine is from autozone. I like the lifetime warranty but I don't wanna be replacing it every 3 months! I got a dealer price of $230 for one of theirs and it only carried a 12 month/12,000 mile warranty. **** that! this alternator does work until you use too much electrical stuff at once. but with the aftermarket stereo and fog lights, on top of the heater and defogger, 70 amps is a little underpowered.
I have a defective one with a bad brush holder that causes the alternator warning light to come on. I wonder if I can beef it up with parts from a more powerful alternator. alternators from the 2nd gen maximas are rated at 90 amps, which would satisfy me, but I think they're physically too large to be installed. I custom-built the one for my blazer (you can tell cos the two end frames are different and the fan is oversized

) and what once was rated at 74 amps now can crank out 130 amps at idle and hover around 14.8-15 volts. let's just say someone returned a tractor-trailer alternator as a core and I parted it out. needless to say, I had to upgrade to 6-gauge wire to go from the alternator to the battery, through an ammeter, to handle that kinda current, cos I have all kinds of lights and stuff that I like to use when I go field hopping lol... and at full electrical load and everything running, I never drop below 14. I love it! but parts to build that alternator were cheap, a new voltage regulator was $12 and brushes were $4. for my nissan, a new regulator costs as much as the alternator itself does.
anyway, I'm gonna check our computer at work and punch in different models of nissan cars and trucks to see what uses a more powerful alternator, and then see if they're physically compatible. I will get through this problem. the SE-R uses an 80 amp, maybe I'll check into that.
