Another generator problem? Two questions?

[thomas_sorrentino]

We had an un seasonable hot weekend here and I was running the gen.
with all three A/C's on. I have the yanmar with the 12.5kw kohler.
Water temp. was runing slightly below 220 degrees (which I haven't
seen that high before). Since this is my first summer with the coach,
my first question is to the guys with yanmars. What kind of water
temp. do you see on yours when running the gen. fully loaded on a 92
degree day?

While we were in the store for a 1/2 hr or so, came out and the gen.
was off. None of the start switches will do anything, no clicking,
nothing. The fuse is good. With the water temp. cooled down, I
disconnected the hot water shutdown, still no cranking. If I hot wire
the fuel solenoid with a jumper and jump it at the starter the gen.
starts fine, runs and produces voltage. I just started looking at the
schematics for the control box and I'm thinking it might be one of
the relays in there. They're labeled CR, C, 1CR and 2CR. Am I on the
right path here? And would anybody know which one would give me these
symptoms? I'm pushing the limits of my abilities here!
Thanks
