Thought I'd post my charging issues in here so as not to start another thread, I've got to check the wiring out with my multimeter yet but was wondering if anyone could offer help with these symptoms.
Basically the car's not getting any charge, and the battery light doesn't come on with the ignition OR when running, it does however come on during (and only during) cranking. When I pulled the alternator apart the brushes looked worn but they're still touching the sliprings with good pressure & I've cleaned them up too. Everything checks out internally, no broken coils etc. I'm just wondering with the absence of charge light except for cranking if it's likely to be the wiring or if the reg/rec/diode pack tend to fail. Hopefully I'll know more once I've tested the pin outputs but just searching for an easy option haha...

I have it wired directly from the alternator to the battery.
Really easy to do. I can take pics if you like but I'm heading to work now and won't be home until really late. Meter shows over 14.0V consistently so now my alternator charges my battery just fine.

Here you go.
Really easy to do, like 3 min job. Need 2 ends that can be crimped and some wires. I used 3 wires (don't remember what gauge) because I didn't have enough gauge wire for the power from alternator to battery. Better than have a little too much wiring than too little and causing heat issues I guess.
