are the terminals next to each other in a row?
im looking at the haynessierra manual now, trying to get my head around it...lol

yes all in a line next to each other.

W is a 12v output, see here, page 8.

the haynes sierra manual seems to suggest that the Alt is used to power a module, such as the electronic choke on a carbed engine for instance, i can only assume this is the W.

That would have been a Blue and white wire. Goes to the choke via a relay driven from the esc-hybrid unit.
