generator won't stay running?

[thomas_sorrentino]

I have a 12.5 Kolher with a Yanmar motor. From any of the switches
the generator will start but as soon as the start switch is released
it stops. I ran a temporary 12vdc jumper to the fuel solenoid to rule
out the safety shutdowns, same thing, it stops. I watched the voltage
gages while I held the switch in the start position to keep the motor
going. No AC registered on the gages and the radiator fan doesn't
come on either. I've had this problem recently twice before, but it
was intermittent and worked again after that, but now its
consistantly not working.
I checked the archives and have seen that other people have had this
problem, but I couldn't find any solutions.
Does anyone have any suggestions? I'd like to get it working before
Maxton!
Does house battery voltage have anything to do with the generator?

p.s. A Kohler dealer e-mailed (pdf file) me the parts manual and
service manuel, which Kinkos put into booklet form for me. If anybody
needs them I can e-mail them to you.
