Ok guys, I got to noticing my alternator is "different" than all the ones in my other cars...It has no fan on it. Its in an 83 GSL, but i was just wondering if maybe its a second gen alternator as I noticed most of those (if not all) dont have fans. Can anyone identify this for me? It came with the car (not installed), and I had to make some custom spacers for it to fit right (mainly cause I didnt have any spacers at all), but maybe the stock one doesnt even use spacers? I dont know...The plug plugged right into it, and it works fine, I was just wondering. Thanks.

My 83 GSL does have a fan on it. I also had to make up a spacer, probably because the last guy who changed it lost the spacer. The idiot put the alternator on anyway, without the spacer, busted the bracket on the alternator, that's why I had to buy a new one from Autozone. Anyway, both the old and new alternator had a fan on it. Did you put the dual pulley on yourself, or did you buy the car that way. I know when I put my dual pulley on, the fan slips right off. Maybe the person who put the dual pulley on, figured he didn't need the fan, and thought he was getting rid of some unnecessary inertia? Just a guess.

 

Nope, I got the car in a box of parts and have been slowly putting it together. The alternator had the stock pully on it, and I was using it that way for a little while. I just got my dual belt pully and installed it myself, so I know that it had the stock pully with no fan. Thats why I was thinking maybe 2nd gen cause it was missing the fan, and it was just thrown in a box with some other parts, I just assumed it was the right one, lol. Hey, at least it works

I believe the 84+ alternators do not have the external fan on them. My GSL-SE ones never did.

 

Good call, bro. I just ran outside and looked at my 85 GSL, no fan . I was thinking of my 84 GS, it has a fan, lol. Ok anyway, thanks for setting me straight. Is there anyway to tell if it might be a second gen though anyway?

The sticker that tells you amperage.

1st gens are like 50 amps.
GSL-SE's are like 55 amps
2nd Gens vary from 65-75 amps.
TII's = 80 amps
FD's = 100 amps
Cosmo's = 90 amps.

 

Wished you had yours runnin', my alt is kinda noisey, I mean not REAL noisey, but doesnt sound like my vert? dunno if its the difference in the small and large case and the power output or not?

 

Mine squeeks just turning it over by hand. So I am probably gonna have somebody look into it. I am not using the seprentine belt though. I got a dual pulley that I had modified to fit the newer alternator. I don't want to use the modfifed (to fit) underdriven Racing Beat pulley for the street, since I have alot of electrical gadgets.

 

GSL-SE is 55amp? That's what I've got then.

 

Does it have a external fan? if it does then its not a SE alt. There seems to be a lot of controversy surrounding the FB alternator. I could have sworn the 83 and older alts were 55 amp, while the 84-5 have an internal fan with 60 amps. But I suppose I could be wrong. Not likke its that important, since I'm running a '89 80 amp alt.

 

Mines 55 amps. All I know is that its not a 2nd gen, and thats all I wanted to know .

Here's a bad pic of my alt:

 

Hey, that looks just like mine .
