Wife's DD so I need to get this resolved or else.
The battery lite comes on real dim and will blink or flash.
Don't think it's the alternator since the system seems to be charging just fine. I'm thinking some kind of feedback from somewhere.
Anyone out there experience something similar?

Could have a bad diode inside the ALT ....

Knew the regulator was integrated, forgot about diodes in the Alternator. Thanks Bamfster.
