Is the alternator charging ? Have you checked the voltage at the battery when it's idling with a multimeter ?
I'm assuming the belt is tight enough and not slipping ? |

Did you change the external voltage regulator? Is it a mechanical or electronic voltage regulator?

Yes, it should have 1. They are usually mounted on the right inner fender or radiator core support. Follow the alternator harness to find it.
Mechanical regulators should be changed every time a new or rebuilt alternators are installed. Electronic voltage regulators are usually reuseable. Quote:

What voltage were you getting with the engine running?
Is your battery good? Was it under load when you checked it with engine off? Got a trickle charger you can top it up with?

Can't be bothered to spell 'Bosch' correctly.
Can't be bothered to speak in coherent sentences or use capitalization or proper punctuation. Can't be bothered to find your vom to do some actual checking on your own. ...Go Fish.

Should be minimum 13.5v running. 12. something means it's not charging.
