Writeup For FD alternator into S4 Sry not enough pictures

okay so i finished the FD alternator installation today and im doing a write up because noone explains this stuff fully and ive come across problems which i had to modify myself so heres my writeup

you will need female adapters, shrink tube or electric tape, a bigger bolt and nut for the adjusting bolt for the alternator and a soddering tool for this
remove TMIC so its easier to take the alternator in and out (OPIONAL).

1. disconnect negative battery cable

2. take off all bolts connecting the alternator on the car. ( should be two )

3. disconnect terminal connections

4. loosen screws/bolts on alternator and disassemble into two ( use a flat head screwdriver taking it off )

5. mount alternator into vice (or something so that it doesnt spin) and take off bolt holding on the pulley ( do the same for the new alternator except you dont have to disassemble the FD alternator. vice the FD alternator by the serpentine pulley. ) (keep the parts seperate from each other dont get it mixed up)

6. vice the V pulley so that it doesnt move and drill the hole big enough so that it would fit onto the FD alternator stud. ( does not have to prefectly fit but somewhat near sense its a V pulley it would get held down by the belt anyways. )

7. next mount the serpentine pulley from the FD alternator into the vice and cut the little spacer out ( you could use a hacksaw ). dont cut to close to it you want it as long as you can get it.

8. after you would want to file the spacer down so its completly flat where you have cut it so your pulley doesnt waddle. ( it doesnt have to be filed down completely flat perfectly just so the pulley wont waddle as much ) . you may have a hard time getting on the spacer all the way down to where it suppose to go on the stud.

9. put the V pulley on and turn it to see if it moves in a still place and rotates good.

10. get a screwdriver and something soft and stick the screwdriver into the alternator into a hole so you can torque the nut holding the pulley ( unless you want to disassemble the alternator and vice it to torque it. )

11. on the old FC alternator remove the B terminal (one bolt ) (see atached) and also remove the B terminal on the FD alternator ( should be one screw and one bolt the bolts under a cap you just pop off )

12. for the FC alternator terminal B you have to grind down the divots ( the plastic circles that stick out on the other side ) use a grinder or a filer if necessary.

13. put the FC terminal onto the FD alternator ( dont worry if it doesnt go all the way down just bolt it on tight )

14. electricals. now for the electrical issue what i did was cut off the origannal connector and got 2 new wires different color approx 6" or a little more and soddered the wires ( the origannal wire colors should be black/white and white/black. DONT GET THEM CONFUSED! ) i soddered the wires on the origannal ones put shrink tube over it and then soddered female adapters onto the new wires. ( make sure they plug in the terminal S and L good before soddering them on the wires ) . then shrink the tube down so it would cover all the wacky wirings up ( you can use electrical tape to ) .

15. find a longer bolt and nut for the mounting bracket . ( if its to long then theres something in the way so dont get that long of a bolt probably 1/4 of a inch more then the origannal. ( you might have to use a washer also so the bolt doesnt go threw )

16. reassemble the alternator on wires plugs in first with the terminal B on ( make sure you keep the black rubber cover on because you dont want to ground it to anything... ) then screw the bolt and nut on first and get a pri bar and lift the alternator up so the belt is tight and tighten the nut and bolt. ( recommend you have someone help you on this ) . then reassemble TMIC. turn on the car and test the charge.

i hope you guys find use of this and i hope this gets archived
