Hello

I'm still struggling to find the fault in my alternator.
I tried two of them.
The first one was working engine cold and once it was hot, I had to give it a big revv so that it would go back to 13.7v. The battery indicator would light up or flicker.

Second one with regulator connected it worked engine cold once hot it goes down little by little until no charge at all. Unplugged regulator it charges when cold and once hot it charges when I drive but then to a stop it no longer charge. No battery indicator with this one.
