Hi all,just done a bottom end swap on my 03wrx for an sti lump.
All back together and running nice,bar the battery not charging!
I've used a alternator flipping kit so alternator is relocated in a/c old place.all wires are connected back okay and all plugged in okay, belt is tight so no slipping either.
The battery light does not come on,on the dash.so guessing a circuit is not being made,is an alternator that fragile I could of damaged it durin removal and refit?? Or is there a wiring fault which is common?? Or has anyone had the same issue? Any help welcome as its killing my brain trying to figure it out! Thanks jake.

not 100% sure but my brother had the same issue with his s turbo, one of the earthing points was fooked, obviously the brushes are fine in the alternator?

Will double check all earth points later,I presume they are okay, it's been fine for a year so woul be very coincidental if they packed up now lol and I was careful with it,never got chucked around at all.thys why I'm thinking wiring incorrect somewhere :-(

maybe something simple as a poor earth, but i hate electrics with a passions as theyre too fiddly

It maybe the flipping kit is not allowing the alternator to earth. run a new earth lead fron battery negative to the alternator body

So the alternator shell itself has to be in contact with an earth?
