Got one. Pm sent.

So I guess this means your going for the ls motor we talked about at msa? You wont be disappointed!

I have one. Ill call you right now.

So heres an update. Havnt been driving the z car because of this issue. I cant afford to destroy another one. I wired in a 100amp fuse (is that big enough?) in line with the wire going from the rear of the alternator. Wire is an 8 gauge. At idle battery is charging around 14.3 That voltage does not move up or down at different rpms. It stays around there. I tried a resistor inline and it does nothing at all. So I uplugged the wire completely "just to see". And the alternator stops charging. Could is be a ground? I dont want to destroy another one. What else should I test?

87 325e. For $400 its ok.

Pics of the bimmer as i bought it. The "canvas" that im about to make my masterpiece.

Got one. Thanks though.

If the ground wasn't good, wouldn't that mean that the alternator would not charge at all? Exciter wire should not see 12vs. It should be no more than 4 volts (and it does see this). Wire guage is 8ga at this time (but it was unfused at the time). Alternator Part # is dl160715-5. Ill test the voltage at 2500 and get back to you on that. Btw where does the white wire go on ur plug in?

Well, it was a hell of a day getting it (yesterday). Saw it on craigslist for $750. 87 325. Drove to lake arrowhead to get it (quite a drive distance wise). But it game a a great feel on the wavy roads. Ended up paying $400 for it. We did get lost of the way back and took the long way home (ended up in hesperia on the other side of lake arrowhead). Car isnt perfect. Not even close. But im in love with e30s. Plans for the car are to be a daily. Cosmetically i want to replicate the e30 alpina b3. Motor plans still in the air. Might slap an "I" head on the m20 motor for now to make a "super eta" motor and give it a little life. Long run I might slap a big six 3.5 (m30 i think is the name of the tag). Pictures will come up soon. For those who have no seen an alpina e30. Here is a pic (happens to be a euro model).

Thing is, I only have one wire coming out of that plug in (red). Alternator charges fine, but the question is for how long before I replace it again. I know there is a prob. So thats kinda why The new alternator is installed but I haven't drove it cause I want to get it right this time. Still wondering how big a wire people normally run, and what size fuse to place on this thing. Still confused whether to put a resistor on the red wire or not. Seems like people who do put a resistor in place have multiple wires coming off the alternator plug in. My harness does not only one exciter red wire (camaro set up). Thanks for the help so far. I think we are on to something.

Just picked up an e30 3 series for a daily. Always wanted one. Finally got it. Pics soon.

Test point would be the back of the alternator? Maybe I should get ahold of one and see...

Sorry for the delay. I exchanged it for a new alternator. Part # is dl160715-5 Its a duralast unit. So should I add a resister to the exiter wire and fuse the battery wire coming from the alternator?

Ill look for the letters on the alternator and post my findings. However I did some reading. Most people fuse the line going from the back of the alternator (150amp). I didnt. Probably should I guess, opinions? btw I still would like to know if the wire im running is thick enough. What do most people run gauge wise? Ill find the letters on the alternator and post the info I find. Reading suggests that camaro alternators need a resistor in place somewhere. Not sure where. Ill find out what alternator I have and figure it out from there.

Hmmm. Thats interesting. How did he test for the spike (multimeter? where was the test point)? Maybe I should give this a shot and see if its happening to me (id like to see if i can test for it first though before i spend more money..)

I am running an exciter wire from the pcm (harness was reworked my speartech if that matters). However the alternator was untouched. It does look much different then s&p version however. Mine only has one red wire coming off of it (it doesn't go to the battery, it goes into the motor harness then the pcm.) According to the service manual it should only see 4-5 volts. Ill have to check it to make sure. Forgive my ignorance, but how does the starter affect the life of the alternator. The motor spins fast and starts up in about 1-2 seconds. Pretty sure the starter is strong but I could be wrong? Another thing came to mind. How thick is the wire that is ususally run from the back of the alternator to the battery? I wonder if the wire im using isnt thick enough?

So here the problem. I have killed 3 alternators in less then a year on the ls1 z car. Cant seem to find an issue. This latest alternator lasted less then a month. Is there anything I should test for? There isn't much that can go wrong on the ls alternator. It grounds to the motor thorough the block. Exciter wire is plugged in fine. The wire from the back goes to the battery. Did a quick test. If i unplug the battery and test the wire its not live when car is running (should be), But when its on the battery it lights up (should be, this shows there are no breaks in the wires). So im running out of ideas. I dont want to keep changing the alternator. I have run out of ideas. Have any of the lsx guys ran into these problems? I know that with the jci mounts you need to "trim" the plastic shroud looking thing to clear the motor mount, so i did that. It does leave the back exposed. Not quite sure if that would cause an issue, but who knows? Talk to me people.

Either or. There is a setting in it to change injector characteristics (At least MSII you can do that anyway).

I believe they are 11mm. But I know they are High impedence. They were used with a megasquirt setup.

Those are o ring type injectors. I meant to say they fit the stock intake not stock fuel rail. Pics in the thread.
