Yanmar oil pressure sender

[thomas_sorrentino]

Ryan,

From my Kohler parts catalog part number 258693 for the oil pressure
sending unit. I've been able to call Kohler gen. parts places, give
them the model, serial# and spec # of the generator and get parts.
(Just ordered new slip rings and trying to work up the nerve to try
to replace them myself).
As far as the gauge not going back to zero. I don't think mine does
either. It stays at where it was when I shut it down, until I start
it again.
