Hrm... I don't see it in the current manual... but it is online in
REV C of the K2 manual. Section 9, page 100.
To save you time though, just remove one turn of the 3-4 winding on
T4. I did this to #1981 and saw an immediate improvement - went from
my K2 battery going dead with 20 minutes to go in the ARS Sprint to
being able to go 2.5 hours.
Amazing what just one turn of wire will do!

I can't find any such section in my Manual or the one online.
Where can I find this?
