Alternator / Rectifier wiring

My recently acquired Le Mans has had its original rectifier replaced with a Lucas version.

This rectifier omits the diode pair that linked to the alternator star point connection.

I can’t see that this connection is necessary, but I can easily re-create it with a suitable pair of diodes wired adjacent to the rectifier.

So do I …

1 Leave it as found with the star point not connected.

Or

2 Fit a diode pair in which case can someone suggest a suitable component or diode rating please.

Thanks.

I am not super brilliant on 3 phase.
I think that rectifying to, and from, the centre point of the star is meant to increase the current capture of the DC system, but i think that in practice t makes feck all difference.

It might be interesting too see if total charge flow increased with that rectified brifge?
