Faulty alternator wiring (help!)

[Dawes]

Hi I have a 92 loyale (with a/c) I have had problems with the alternator ground wire having a bad connection... And I'm guessing you all know how that turned out. Fixed that and I had bad alternator symptoms once again. So my question is.. After I test the alternator I'd like to replace the wiring is that something I can buy at an auto parts store.. Or should I just add new connections and hope it won't happen again? Thanks!

On xt6's I buy a generic connector to replace the alternator plug.

 

Stock wiring isn't available. Or see if Subaru carries it but that's likely to be $$$&$$&

Gday Dawes,

If you are using the original Hitachi Alternator unit, you should be able to buy just about everything at your local parts shop. Failing that, go and see your local Auto Electrician.

 

The main charge lead (white) that goes to the B+ terminal on the back can be replaced with 8mm cable and run directly to the Positive battery terminal. Standard Yellow Crimp connectors will take 8mm cable if you are careful not to bend the strands as you insert them. Failing that, get your hands on some 10-6 or 10-8 cable lugs and crimp those on using lug crimpers or big pliers or crimp in a vice and solder.

 

The 2 pin plug is commonly called a male QC2 connector. Dunno if you fellas have Narva branded stuff over there in the states, but if you do the number is a 56252. This plug will have two conections to it, L and S. The S wire you can run a 3mm cable to a fuseholder, and then directly to the battery. Use a 5 amp fuse.

 

The other wire, L, will run all the way to the instrument cluster. In reality, the load on that circuit is so insignificant that the cable is probably OK. If you really want to replace it though, you will have to pull a new wire back to the instrument cluster and I cant remember what pin you need to connect it to off the top of my head. (Ill look up my notebook later)

 

As for an earth lead, run a 8mm cable from the alternator top adjuster bolt to the negative battery terminal.

Nope that helps.
