I recently bought a 85 gsl.The previous owner thru in a 94 altenator.Ive look around but i couldnt find any old post.If you could help me with the wiring or lead me in the wright direction.The system ive installed it might be to much for that 50 amp.

 

a 94 alt is MORE Than enough. do you need to know how to wire it. search 3rd gen or S5 alternator. i have a FD alt in my 85 GSL. if you dont find anything ill give your pics and details on how to do it tomorrow.

 

Here ya go.

 

^^ exact diagram i used. DONT jump the S and B terminals. it seems logical but will cause your alt to pull power from the battery even when the car is off. leaving you with a dead battery if your car sits for any time. just FYI

 

I know this is an old thread but I've got a question on it. Are you sure that you can't jump B to S terminals? I wired my old S4 turbo that way and never had a problem. I'd like to avoid killing the battery in the "new" car but do I really have to run a second wire to the battery? Is this a first gen thing only? Any help is appreciated.
