Now guys ! Go easy on me ! I am not a professional and I accept my

12V regulator and so should not make a difference.

I will get a proper regulator and try it on. Will post back with
results.

off the top of my head, it doesn't sound like a completely impossible
idea... i haven't seen a separate regulator on a car in a long time.
where did you get it? maybe it's dead?
