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.

 

checked all your earthing points?

 

There's one earth on the inlet manifold,and one just above battery.is there anymore?

 

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

 

I think it must be something stupid.but I haven't got the patience for electrics I bloody hate them too!

 

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?

 

earths on the engine

 

Yes.

 

Well that's why then! new bracket is powder coated so will be no connection! Will check tonight after work and see how it goes.thanks

 

yep was the powdercoat on the alternator relocation bracket i bought,cleaned off on contact areas and all up and running again
thanks for your comments guys.much appreciated

 

Cool

 

feel like a tw*t for not realising but hey live and learn! cheers

 

Nothing to feel bad about. We're all on a learning curve. Just happens electrics are my thing. But i cant do bodywork. Lol

 

dont think ive got a "thing" lol
