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...
