i've had my 89' 240sx for 3-4 years now and gone through atleast a battery or two a year, that aint right. and i wasn't just buying the cheapest piece of crap i could find either..
anyways, my battery keeps getting drained by something and i can't figure it out. just put in a new one earlier today as well, sposed to last atleast 3 years, we'll see.. har.. alternator's been tested good at autozone too, connections are all fine, did a voltage drop test, that was fine. did a parasitic draw draw test and i was over 100mA, that's a bit high, from what I understand it should be below 25-50 or so mA.. yanked the 75A FL Alt fuse and it went way down to a more normal reading. I can't figure out what's going on. And yeah, fuse itself looks fine as well, looked in the little plastic thing at the top and the metal's still connected and all.. Also, just incase I'm an idiot, that's the first time I've done a parasitic draw test. it is 25-50 mA I'm aiming for right? I don't want to go through this hassle thinking that I'm narrowing down the problem just to to find out I missed a decimal point\zero and that it's 250-500 mA, then the 100 mA wouldn't be so bad lol..
my battery drains fast though, if I just don't drive it for a week, it'll be dead next time I try to crank it up..
there anything aside from the alternator on that 75A FL? I've been going back and forth through the FSM trying to find info on it, but I've got a feeling I may just be looking for something that isn't there lol.. But if there's only the alternator on there, then I'd assume it's either gotta be the alternator or something crappy with the connection that i'm not noticing..
I'm going to take it back to autozone and get the alternator, voltage regulator, and charging system tested again, just incase. On a side note, anyone know specifically what their alternator test actually tests for? I had another guy suggesting that the rectifier may be flaking out, but he worked in an auto electric shop and wanted to charge me just to take a look at it, and when I asked how much it'd run "I don't know, it could cost anything" ... Don't wanna pay some jerk $300 when I can buy a new alternator for $105 lol.. But, is that a possibility? Autozone's test not test it that thoroughly and there still a possibility something's screwed with it causing the drain even if it passed the test?
any help\ideas\suggestions would be much appreciated, this thing's driving me nuts lol.. thanks
