[AT] Winco generator question

[Ken Knierim]

Howard,
    Thanks for the link... lots of information in there. Still need to see
whether they have one for my exact model (a 13kw unit with a Wards label).
As far as a rectifier, mine came with 4 individual aluminum clad diodes
that were clamped down (kinda rickety but worked I guess) and I replaced
them with a single bridge rectifier. Since DC needs to go to the field from
the rectifier, it wasn't hard to take my old battery charger and make sure
the field had been flashed.

Hope this helps.
