No Greg,
I don't have a part number, but Jim and Kevin's input has helped.
It appears that the I terminal needs switched 12V, the L terminal is the
charge lamp signal, and the S terminal gets battery 12V along with the B+.
There was a thread on the MGB forum about this same ND alternator
highlighting that if the S terminal isn't seeing battery voltage, you don't
get full 14+V output, so I've wired it to the B+ terminal as well.
This was supposed to be a 1 wire alternator, but it's what I've got, so I'm
working it out.
Thanks to everyone who has offered input.
I'll report back about this after I finish the rest of my mod adaptations
and get it running.
