3G Revisit September 19, 2007, 11:37:37 PM Okay I have read over every possible 3g alternator install, and i understand everything about it except for one thing. Everyone mentions this wht/blk wire (stator), well this wire isn't on my car or is in wrong place cause i cant find it. My power connector coming off alternator has 2 power lines that ultimitly make it to the starter switch through fuse-links. There is not a 3rd wire that is on this connector. After looking at the 2.3s diagram posted recently, my setup looks like it. The regulator connector has 3 wires, and one of them is black and is only 3" long and then just stops inside the tape. Whats the deal? Should I just skip the stator connector or what?http://i220.photobucket.com/albums/dd167/ztrane/IMG00170.jpghttp://i220.photobucket.com/albums/dd167/ztrane/IMG00163.jpghttp://i220.photobucket.com/albums/dd167/ztrane/IMG00159.jpg Quote Selected
3G Revisit Reply #1 – September 20, 2007, 12:55:16 AM it should be on the "d" shaped plug with the green, and yellow wires. the black wire in your pic is probably the one it goes to. green wire goes to dash, yellow wire goes to stud on back of the alternator.maybe a previous owner changed the wiring pigtail with a parts store piece, and it wasnt color-coded correctly.

I still cant figure out why, although i have looked at the three different motor wiring layouts and they all seem to be easy enough to follow.Me thinks someone with a 3g on a 2.3 aught to copy/paste the final draft inside the 3g sticky and modify its layout to reflect the 2.3.that would be helpful.

3G Revisit Reply #3 – September 20, 2007, 09:32:14 AM It shouldn't matter what car it matters more what style alt from the factory 1G or 2G? Then it is just different wiring. With the 2g style that you have in the pics you just need to find the S stator wire. That should be the center wire. Regulator should have lettering with the standard ISA on it. Splice another wire onto the S wire. Run the new wire to the single wire plug on the 3G alt. Then get rid of the Big rectangle plug and run your 4ga wire with inline fuse. Another thing that might be confusing is that the older style external regulated have a D shaped plug for the wires running to it. Quote Selected

3G Revisit Reply #6 – September 20, 2007, 11:28:24 AM Unfortuanatly no just black and was wrapped up in tape with other 2 wires from factory, removed tape and found that the black wire is only 3" long and just ended. What does the stator do? I mean the wire, cause maybe there is a way to test if its the right wire... Quote Selected

3G Revisit Reply #9 – September 20, 2007, 09:50:54 PM If your car has an ammeter, the S input to the regulator is not used in the stock setup.The three wire setup is used when you have an indicator lamp(idiot light) on the dash.The I on the regulator stands for indicator switch.For an alternator to produce voltage when it starts turning, the field has to be energized or in alternator parlance "excited".Applying voltage to either the I or the S will excite the alternator.When used with an indicator lamp the exciter voltage comes through the lamp to the I on the alternator. This provides ground to light the lamp and excites the alternator.When the alternator is running the stator terminal provides a voltage equal to half the output voltage. When this voltage is applied to the S on the regulator it takes over exciting the the alternator and opens the indicator switch. The lamp goes out.Since you have no indicator lamp they excite your alternator with the I and don't use the S.It doesn't hurt anything if you hook up the stator to S but you don't need it.Why they put that pigtail wire on the S I have no clue. Unless it is the just fill up the connector so it doesn't look like something is missing. Quote Selected
3G Revisit Reply #10 – September 21, 2007, 02:08:28 AM In addition, there are leaps and bounds differences between the 87 and down TC with respect to the lonely 88 tc with reguard to the 3g upgrade.I really think this needs settled once and for all so no more fires happen. I was just talking about this issue with tom and we agree that there should be a special layout for "half motors":evilgrin: and for the half motors, the instructions should be in two parts.One diagram for the 87 and downOne diagram for the 88I dont think im the man for the job because i dont have first hand tinker time with the TC ,, i thinks someone in the tc arena should step up and geter done.

It started up and I tested battery and alternator to chassis and only got 12.4 at best. Not much of an increase, not to mention my windows are much slower, especially passanger side. Other than that, it is smooth. My old one was unbalanced and had excessive wobble (made the clickdy sound when speeding up). No wires are hot, I pray:bowdown: to the cougar gods to not lite my alternator regulator on fire. Quote Selected
3G Revisit Reply #13 – September 21, 2007, 06:12:36 PM dude, you need to wire it up correctly. use this diagram:you may need to go buy a pigtail from a parts store or get one from a junkyard. take electrical modifications VERY seriously. Quote Selected
