Thanks for the reply Melanie. Your speaking in mA, so obviously this isnt the source of my problem. I am experiencing major power consumption, enough to dim headlights, etc.
The circuitry I speak of is in an old mustang, so power comes at a cost. I suppose its time to just bite the bullet and get a new generation alternator upgrade.
I am slowly upgrading those high consumption interior, exterior lights for LED's. Great success so far.
