The Onan has two rectifiers; one of them rectifies 12 v to charge the
battery and the other provides high voltage DC for the field windings of
the generator. The 12 v one is redundant and unneeded in our application.
The field current is necessary for generator function and no voltage at all
is produced when it fails.
When my field rectifier failed a couple of years ago I couldn't find an
exact substitute so I stayed with the Onan part. I believe I could find a
substitute part but the pin out wasn't an exact match. My logic was that
this part is mission critical and I want to be able to repair it or get it
repaired while on the road where I don't have a shop. Hence stock Onan parts.
The last two years I've had the Onan fail while on vacation. Wife sez one
more time and she's going to donate the whole Green Weenie to Pack Rat
Central. So keep it fixable.
OBTW: Note that I've changed ISP's and have new address.
