When the battery was installed did you reset the BMS? You'll need a GAP tool or similar to do this.

Recheck all your connections.

Also, which went first? Battery or alternator?

Where is the alternator from, what brand etc.

Try running a temporary extra earth from an earth point to the body of the alternator.

Did you plug in the sense wire at the battery negative post properly?
