kansascity1 Posted December 3, 2007 Report Share Posted December 3, 2007 I will double check everything tomorrow, I will try and look at the 620 and 510 schematic to find out which wires will work for everyones application :D which alternator is that? how about a 521 also for wiring Quote Link to comment
datzenmike Posted December 3, 2007 Report Share Posted December 3, 2007 I think the 90's KA truck alternator might be a little bit smaller, the idler arm is very close on the trucks, I had to run a smaller belt to clear it. Just something to look out for. I have a pic of all 3 somewhere I will try and dig them up tomorrow. Here ya go Jeff, is this it? 521/ 620/ KA alternators http://i138.photobucket.com/albums/q251/datzenmike/altornaters.jpg[/img]"] Quote Link to comment

slodat Posted December 3, 2007 Report Share Posted December 3, 2007 I picked up a couple of pulleys from an independent alternator rebuilding shop. Quote Link to comment
hang_510 Posted December 3, 2007 Report Share Posted December 3, 2007 ^any extras? could you include a 'big one'? :lol: i will try an alt shop too... Quote Link to comment
laniadude Posted December 4, 2007 Report Share Posted December 4, 2007 So If I get that alt from the 90's Saturn, I can elminate the voltage regulator that's bolted next to the battery? Quote Link to comment

I'm talking to ]2eDeYe in PM's about this so I will post what I get out of him in here, if he doesn't answer your question first. Quote Link to comment
Icehouse Posted December 4, 2007 Author Report Share Posted December 4, 2007 which alternator is that? how about a 521 also for wiring It is off a nissan 240sx that is why the fan belt is multi grove. The ka in the nissan pickup has a v belt pulley. I just used it for the wiring pic since all the alternators are the same in the plug department. Like Slodat says in early posts the Schucks alternators are junk! I had to buy one to make it to work, but if I was in your situation I would go with the saturn or a factory nissan unit. I like the TRUCK ka one because it bolts up directly to the factory datsun brackets. Just make sure the fan belt is the correct length so it doesn't hit the idler arm. I have 20k on my Schucks unit, I'm amazed! :D Quote Link to comment
irsa76 Posted December 4, 2007 Report Share Posted December 4, 2007 Please tell me the bigger alternators are simply longer. Don't forget I've got a steering box to get in the way. I know I need to upgrade the electrics in this thing, I'm nightblind. I'm thinking of running about 570watts of high beam, not to mention my 55w fog lights. Quote Link to comment
]2eDeYe Posted December 4, 2007 Report Share Posted December 4, 2007 Nope, not longer sorry...they are bigger in diameter. Once you wire the alternator for Battery (big post) ignition and charge light the regulator can be unplugged and thrown away. Quote Link to comment
kansascity1 Posted December 5, 2007 Report Share Posted December 5, 2007 This is the one I bought, is it the right one or will it work? It is for a 1994 Saturn SL2. http://www.autozone.com/R,APP185892/vehicleId,1968501/initialAction,partProductDetail/store,3150/partType,00086/shopping/partProductDetail.htm The only thing I'm not sure of is where the plug goes, and how to wire into it. It has 1 big pron and 3 little prongs. Any ideas? Quote Link to comment
]2eDeYe Posted December 5, 2007 Report Share Posted December 5, 2007 I forgot to mention in my PM to get the plug from a j/y It will save you a bit of hassel in the long run. Quote Link to comment
kansascity1 Posted December 6, 2007 Report Share Posted December 6, 2007 yeah, I'm gonna try to hit them up this weekend. I talk to the Saturn dealer about the plug, and the wanted $64.90 for it. Quote Link to comment
kansascity1 Posted December 6, 2007 Report Share Posted December 6, 2007 Does anybody have any idea where to find a wiring diagram for an AC Delco alternator (for the internals)? I have been messing around on the AC Delco site as well as the Delco Remy site and I can't find anything. I am trying to figure out what prong does what on the plug. Quote Link to comment
slodat Posted December 6, 2007 Report Share Posted December 6, 2007 Google? As Steve said above, you wire the larger wire to the output of the alternator and the smaller one goes to the light circuit. If you are having problems with it I can't recommend MAD Electrical enough! He makes it even easier. I'd still get the plug from the bone yard. It can come off of ANY CS alternator. 1 Quote Link to comment
kansascity1 Posted December 6, 2007 Report Share Posted December 6, 2007 Google? As Steve said above, you wire the larger wire to the output of the alternator and the smaller one goes to the light circuit. The plug has 4 prongs on it though. I found a place that has one of these cars, so hopefully tomorrow I can get the plug. Quote Link to comment
slodat Posted December 6, 2007 Report Share Posted December 6, 2007 I'm not trying to be rude, but you seem like you would benefit from the MAD Electrical install guide. Wiring this alternator is dead easy. There are two wires on all of the pigtails I have. I understand that the connector in the voltage regulator has 4 pins. That doesn't have a damn thing to do with the fact that it's STILL raining in the NW. Quote Link to comment
kansascity1 Posted December 6, 2007 Report Share Posted December 6, 2007 I'll check it out Quote Link to comment
]2eDeYe Posted December 6, 2007 Report Share Posted December 6, 2007 Wet outside.... :P Quote Link to comment
kansascity1 Posted December 13, 2007 Report Share Posted December 13, 2007 Well, I finally got the swap done. Thanks alot to ]2eDeYe for putting up with a lot of stupid questions and having to explain stuff to me. It's working great I can run my compressor, high beams, and stereo with a 600 watt amp pushing 1 12" Fosgate and it hasn't missed a beat. Thanks all for the help. 1 Quote Link to comment
]2eDeYe Posted December 13, 2007 Report Share Posted December 13, 2007 Best upgrade there is...you can thank slodat as well. He's the one that sourced the Saturn alt. origionally ;) Quote Link to comment
kansascity1 Posted December 14, 2007 Report Share Posted December 14, 2007 well then.....Thank you SloDat! Quote Link to comment
fiveNdime Posted December 14, 2007 Report Share Posted December 14, 2007 This is another great thing about nissan. I have a friend that wired up a one wire 90 amp GM alt. Worked good for him. I personally used my stock Z22 alt in my KA swap into my 510. I just swapped pulleys off the KA to the Z22 alternator and hasnt missed a beat yet. I will upgrade soon though just not enough juice for a stereo system. Quote Link to comment
laniadude Posted December 18, 2007 Report Share Posted December 18, 2007 Is this the 90 amp that works??? http://cgi.ebay.com/ebaymotors/1997-97-SATURN-S-SERIES-90-AMP-ALTERNATOR_W0QQcmdZViewItemQQ_trksidZp1638Q2em118QQcategoryZ33573QQihZ001QQitemZ110174839648QQrdZ1QQsspagenameZWD1V Quote Link to comment
