Lucas Alternator Wiring - Sense Check

[adrianreeve]

Am I right in thinking that with my Lucas alternator with two big spade terminals and one small, that the small goes to the dash light, and either one of the large spades goes to the battery, or do they both need to go to the battery? I seem to remember someone saying that the two large spades are connected internally anyway. Also, does it need a seperate earth, it doesn't have an earth connection, so I'm guessing not.

Cheers
