Dummy dash battery light is on dim at idle and brightens as rpm
increases.
Belt tension is OK, battery reads 14.4 V (alternator seems to be
working) when charging.
Battery is at approx 12.6V after sitting.
Car has stalled a few times when turning but can be started right back
up.
I was thinking I have a bad ground to the engine block ?
Might just change the cable from the battery to the block but thought
I would ask for people's comments.
Thanks in advance.

Have you cleaned your battery posts and cables?

Had the alternator TESTED? (Kragen, PepBoys & so on test for free)

Thanks for the response.
Battery posts and connectors are spotless, battery was slow charged on
a charger and the alternator was rebuilt and tested.
I have contacted the alternator shop and I am getting it re-tested
this morning.

It's a bad VR light output transistor

I got a rebuilt alternator with the same problem. Since I could tell that
the alt was working from the dash voltmeter, and a DVM check at the terminals
confirmed that. I have just driven it with the lite on.

Too much trouble changing pulleys

I pulled the second wire off my aftermarket one wire alternator ...
light is now off. I hated having to spin the alternator to get it to
start charging but I am no longer blinded by the light.
Thanks.
